Description

Orthopedic spreading forceps

technical field

The utility model belongs to the technical field of medical appliances, in particular to a spreading forceps used in orthopedics.

Background technique

At present, retractors are often used clinically in orthopedic surgery to widen the surgical field of view. The retractors used in orthopedic surgery are mainly composed of the retractor arm, the hook body and the tooth process at the lower end of the hook body. The existing retractors generally only use a single tooth process during use. The center plays a role of fixation. Because most of the orthopedic surgery pulls ligaments and other elastic tissues, only one tooth process is not firmly fixed, and it is easy to slip off. Ligaments and muscles are relatively thick, which makes the stretching process very laborious, time-consuming and laborious, and increases the difficulty of work for medical staff, so that the quality of the operation cannot be guaranteed, and the use effect is not ideal.

A retractor for orthopedic surgery disclosed in Patent No. 201220144897 is characterized in that it includes a pull arm, a hook body, a pull handle, a depression, a denture, and a tooth ring, and a pull handle is provided at the rear of the pull arm. The front part of the arm is provided with a hook body, the front part of the hook body is provided with a gear ring, the front end of the hook body is provided with tooth protrusions, and the handle is provided with a depression, and the depression is adapted to the size of the belly of a finger. Its disadvantages are: 1) it needs to be pulled by hand during use, and the pulling process is very laborious, time-consuming and laborious, which increases the difficulty of work for medical staff, thus cannot guarantee the quality of the operation, and the use effect is not ideal. 2) To open the wound, two of the above-mentioned hand pull hooks must be used, which requires additional medical staff. The space of the operating table itself is small, and too many people will make it difficult to observe the wound, which increases the difficulty of the work of the medical staff and cannot guarantee the operation. quality, the effect of use is not ideal.

Utility model content

The utility model aims at the above-mentioned deficiencies in the prior art, and provides a spreader for orthopedics, which is easy to use, does not need to be pulled by medical staff, can stretch the wound, and the spreader is firmly fixed and not easy to slip, fully exposing the surgical field of view, Thereby improving the quality of surgery.

In order to solve the above-mentioned technical problems, the technical proposal of the present utility model is: an orthopedic spreading forceps, comprising an upper forceps body and a lower forceps body hinged thereto. Conical thorns, the tail ends of the upper pliers body and the lower pliers body are provided with nuts, and the two nuts are connected by a screw rod, and a rotating handle is arranged on the screw rod.

A rotary handle is arranged in the middle of the screw rod.

The rotary handle adopts a telescopic rotary handle, and a tapered thorn is arranged at the end of the telescopic rotary handle.

Scale marks are set on the screw rod.

The orthopedic stretching forceps adopting the above scheme is provided with positive and negative wires on the screw rod, and several conical thorns are arranged at the front end of the forceps body, which increases the contact area with the flesh and increases the friction force so that it is not easy to slip; the screw rod There is a rotating handle in the middle. When in use, turn the rotating handle, and the pliers body will expand and contract quickly, which is convenient to use; stretch the telescopic rotating handle and support it on the wound. It is more convenient for medical staff, the field of view of the wound is large and easy to observe, which reduces the work difficulty of medical staff, ensures the quality of the operation, and has an ideal effect; the end of the telescopic rotating handle is equipped with a conical thorn, which increases the contact area with the flesh and increases the frictional force , so that it is not easy to slip off. Calculated by a certain ratio, the scale line is set on the screw to facilitate the measurement of wound data. Therefore, the utility model is simple and practical, saves time and effort, is convenient to operate, shortens the operation time, reduces the doctor's operation burden, reduces the operation risk, and has good promotion and application value.
