Description

periosteal dissection stopper

technical field

The utility model relates to a stripper used for medical operations, in particular to a periosteum stripper with a blocking function.

Background technique

Periosteal stripper is one of the most commonly used orthopedic instruments. During orthopedic surgery, it is necessary to partially strip the periosteum at both ends of the fracture, and sometimes it is necessary to perform extensive periosteum stripping to push away the muscle tissue and avoid it blocking the surgical field of view, which is conducive to exposing the fracture. position, so that the fracture can be reduced under direct vision, which is conducive to the placement and fixation of internal fixation objects (such as steel plates). Existing periosteum strippers generally include a hand-held part, a neck and a peeling head connected in sequence. The hand-held part is the operation site for medical personnel during surgery. The peeling head is in direct contact with the periosteum and has a blade to facilitate peeling. For connecting the handle and peeling head. The lower border of the mandible in the human body is passed through by the facial artery, the marginal mandibular branch of the facial nerve passes through, and the surrounding masseter muscle attaches to the air larynx jugular artery and vein and its branches ascending, so the anatomy is complex. At present, when using the existing periosteal stripper for submandibular incision surgery, especially in the process of osteotomy, the important blood vessels are often contused due to inadvertent operation, causing massive bleeding, and the mandibular branch of the facial nerve, causing damage to the mandibular branch of the facial nerve, which brings great harm to the patient. Sequences such as crooked mouth corners, bulging cheeks, air leakage, and salivation affect their diet, facial expression muscle function, and facial appearance, reduce the efficiency of stripping during surgery, prolong postoperative recovery periods, aggravate patients' pain, and increase medical costs.

Therefore, there is a need for a periosteal stripper with a blocking effect, so that it can avoid stripping the head and contusing the mandibular marginal branch of the facial nerve during submandibular incision surgery, reduce side injuries, improve the stripping efficiency of the operation process, and shorten the postoperative recovery period , reduce the cost of treatment while relieving patients' pain.

Utility model content

In view of this, the purpose of this utility model is to provide a periosteal stripping stopper, which can avoid stripping the head and other osteotomy tools from contusing important blood vessels and nerves during submandibular incision surgery, reduce side injuries, and help expose the operation area , Improve the stripping efficiency of the operation process, shorten the postoperative recovery period, reduce the pain of patients and reduce the cost of treatment at the same time.

The periosteum stripping stopper of the present utility model comprises a hand-held part, a neck and a stripping head which are sequentially connected, and the neck is connected with a limiter which can be stuck on the bone edge of the human body and is used to limit the stripping range of the stripping head body.

Further, the surface of the neck is partially protruded to form the limiter.

Further, the stripping head is flat and concave arc-shaped along the length direction, and the limiting body is located on one side of the neck axis.

Further, the limiting body is arranged at the end of the connection position between the neck and the stripping head, and the side of the stripping head is connected to the limiting body in a smooth transition, and a Pu-shaped cutting edge is formed at the connecting position.

Further, the edge of the cutting edge is a flat edge.

Further, the handle is a handle with an anti-slip mechanism, and the upper end of the handle is provided with an arc-shaped groove that fits with the fingers of the human body, and the arc-shaped groove is directly processed on the upper and lower surfaces of the handle. become.

Further, the anti-slip mechanism includes straight grooves arranged at intervals and extending from the bottom end of the handle to the end of the arc-shaped groove, and the straight grooves are directly processed on the upper and lower surfaces of the handle. become.

Further, the handle, the neck, the peeling head and the limiter are integrally formed; this improvement can also be replaced by, the neck, the peeling head and the limiter are integrally formed, and the neck is detachable connected with the handle; as an improvement to this alternative, at least the lower end of the neck is in the shape of a round rod, and the neck extends coaxially into the handle and is threaded.

Beneficial effects of the utility model: the periosteum stripping stopper of the utility model, by adding a limiter, the limiter is blocked by the bone edge of the human body during the submandibular incision operation, thereby limiting the peeling range of the peeling head, and the peeling head The combined effect of the head and the limiter can play a multi-functional role, among which it can prevent the peeling head from contusing important blood vessels and nerves, reduce side injuries, improve the stripping efficiency during the operation, help fully expose the operation area, and shorten the postoperative recovery period. Reduce the pain of patients while reducing the cost of treatment; in addition, different types of periosteal dissection stoppers have different positions on the neck, so that they can be selected according to the conditions of different patients or different surgical procedures; The new type has simple structure and convenient use, is suitable for various orthopedic operations, and has strong popularization and application value.
