Intended Use

The EuTrochar is a trocar used for the installation of surgical drains.

Device Story

EuTrochar is a stainless steel, curved trocar used for surgical drain installation. Device consists of a sharp-pointed rod and a 'Deployer' handle mechanism. Unlike traditional trocars requiring manual removal of protective covers and use of pliers, the EuTrochar uses a Deployer handle to house the trocar and a protective 'Sheath'. Surgeon places the Deployer at the desired exit site; squeezing the handles advances the trocar through soft tissue into the Sheath, which acts as a target. This mechanism keeps the surgeon's fingers away from the sharp point, improving safety and placement accuracy. Once the drain is positioned, the trocar is cut from the tubing and discarded. Used in surgical settings by surgeons and assistants to facilitate drain placement without manual handling of the sharp point.

Clinical Evidence

Bench testing only. Testing performed on prototype hardware using plastic tissue and animal tissue models. A 'bench trial' protocol was conducted using plastic sheets to simulate tissue. No failures were reported in these trials, and the device was deemed safe for patients and surgical personnel.

Technological Characteristics

Highly polished stainless steel rod, curved geometry (approx. 160mm length, 4-6mm diameter). Includes a mechanical 'Deployer' handle and 'Sheath' protective cover. Manual operation; no energy source. Non-electronic, mechanical surgical instrument.

Indications for Use

Indicated for the installation of surgical drains in patients requiring surgical drainage. Prescription use by surgeons.

Regulatory Classification

Identification

A manual surgical instrument for general use is a nonpowered, hand-held, or hand manipulated device, either reusable or disposable, intended to be used in various general surgical procedures. The device includes the applicator, clip applier, biopsy brush, manual dermabrasion brush, scrub brush, cannula, ligature carrier, chisel, clamp, contractor, curette, cutter, dissector, elevator, skin graft expander, file, forceps, gouge, instrument guide, needle guide, hammer, hemostat, amputation hook, ligature passing and knot-tying instrument, knife, mallet, disposable or reusable aspiration and injection needle, disposable or reusable suturing needle, osteotome, pliers, rasp, retainer, retractor, saw, scalpel blade, scalpel handle, one-piece scalpel, snare, spatula, stapler, disposable or reusable stripper, stylet, suturing apparatus for the stomach and intestine, measuring tape, and calipers. A surgical instrument that has specialized uses in a specific medical specialty is classified in separate regulations in parts 868 through 892 of this chapter.

Trade Name, EuTrochar

Common Name, trocar for installing surgical drains

Name of legally marketed devices.

The Davol Reliavac with PVC Drain, DVL3463 TLS Surgical Drainage System, 7 French Drain Kit trocar. Catalogue Number 6640.

Description. The EuTrochar is a trocar used for the installation of surgical drains. The EuTrochar has a handle, the "Deployer" to facilitate gripping, to improve accuracy of drain placement and to keep fingers away from the sharp point. Trocars have been used for more than a hundred years to create an incision in soft tissue for surgical drain tubing. Like other drain installation trocars, this instrument is a highly polished stainless steel rod of small diameter, normally 4 to 6mm in diameter and about 160mm long. One end of the rod is very sharply pointed and the other end has a hose barb for affixing tying. The rod is curved between the two ends so that it looks like a giant sailmaker's needle.

Intended Use. The EuTrochar is a trocar used for the installation of surgical drains.

Summary of technological characteristics of the device compared with the predicate devices. Like other drain installation trocars, this instrument is a highly polished stainless steel rod, curved in the middle of the length and having a sharp pointed end and a second end for tubing attachment. Beyond the similarities, there are several differences between the EuTrochar and predicate drain installation trocars. Predicate drain installation trocars have a soft plastic cover over the sharp pointed end. This cover must be removed before use. The surgeon or surgical assistant pulls this plastic cover off. Then, grasping the trocar in his hand or with pliers, the surgeon pushes the point into the area where he wants the drain tubing and forces the predicate trocar from within the surgical incision, through soft tissue to the outside. When the sharp pointed end emerges from the outside tissue, the surgeon typically grasps the emerging pointed end using pliers. He then pulls the trocar through the tissue flap and with it, on the trailing end of the trocar, comes the drain tubing. After cutting the trocan from the drain tubing, the surgeon or assistant must replace the protective cover onto the sharp point.

The EuTrochar is different from the predicate drain installation trocars in that the protective cover "Sheath" is not removed by the surgeons' hand. The protected EuTrochar, (Sheath covering the sharp point) is inserted into a handle, ("Deployer") into which it is automatically securely fastened. Grasping the Deployer by the handles, the surgeon opens it, releasing the EuTrochar from the protective Sheath remains in the head (Receiver) of the Deployer and acts as a target for the sharp point when later the Deployer is closed, returning the sharp point on the EuTrochar into the Sheath. With the Deployer opened, there is ample clearance tissue to fit between the sharp point of the EuTrochar and the Receiver target. Holding the Deployer by the handles, the surgeon and associates are clear of the sharp point as it is placed at the desired spot for the drain inside the soft tissue flap. The Deployer is positioned such that the target is placed at the desired exit position of the drain tubing. Squeezing the handles closes the Deployer and therefore advances the EuTrochar through the soft tissue and back into the Sheath. Since the target supports the tissue, the EuTrochar is advanced through the soft tissue, without fingers or hands near the

sharp point. And, the drain tube will be in the exact position desired by the surgeon. The Sharp point of automatically locked into the Sheath when the Deployer is closed. The tubing Eurrochar is and drain tubing through the soft tissue. No fingers come close to the point, as it is enclosed with the Sheath. When the tubing has been pulled far enough, the EuTrochar, protected by the are work.
Sheath, is easily released from the Receiver. It is cut from the tubing and discarded into the hazardous waste depository.

Thus, the differences between predicate drain installation trocars and the EuTrochar are in the protective cover over the sharp point and in the handle (Deployer) which replaces the need for pliers and keeps fingers clear of the sharp point.

This product has no Performance Standards. Technicians in Special Devices performed exhaustive tests with prototype hardware using both plastic tissue and animal tissue. Many drain installations were performed on dead animal tissue. Additionally, as an aid to writing the Technique Manual and to ascertain that the hardware could be used successfully by outside surgeons and support personnel, Special Devices developed a Trials Protocol, which we consider a "bench trial." Employing plastic sheet as ersatz tissue, a series of EuTrochars and several Deployers were used in trials. No failures were experienced.

The conclusions of each tester were that there had been no failure and that the devices did not present a hazard to a prospective patient nor to surgical personnel.
