Description

A microsurgical point-like spreader

technical field

The utility model relates to the field of medical instruments, in particular to a microsurgery point-shaped spreading forceps.

Background technique

Nowadays, in hand and foot microsurgery, in order to expose the wound surface and obtain a wide surgical field of view, the skin at the wound margin and the normal skin at the far and near ends are often sutured and fixed to expose the wound surface; Superficial vein damage is serious, which reduces the veins available for anastomosis, resulting in postoperative reflux obstruction and even surgical failure; moreover, suturing with the normal skin at the distal and proximal ends is also a kind of damage; sometimes the exposure is not enough and needs to be sutured again, which wastes operation time; and the exposure is excessive It is easy to cause excessive tension in blood vessel suture or cannot be sutured directly. It is necessary to remove the suture and re-suture and fix it, which will increase the operation time. For this reason, we have developed a microsurgical point-shaped spreader to expose the wound surface through the opening of the jaw. , and the tissue damage is small when the jaws are opened, the size is convenient to control, convenient to adjust, safe and reliable, thereby saving operation time.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a microsurgical point-shaped spreading forceps, which exposes the wound surface through the opening of the jaws, and the tissue damage is small when the jaws are opened, and the size is convenient to control and adjust. Safe and reliable, thus saving operation time.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a microsurgery point-like spreading forceps, comprising a left forceps body and a right forceps body; the left forceps body and the right forceps body are intersected and hingedly connected; The pliers tips of the left and right pliers are respectively provided with outwardly curved arc-shaped traction hooks, and rotatable lead screws are respectively arranged inside the pliers handles; the lead screws on the left pliers and right pliers pass through The adjusting nut is connected; during work, turning the adjusting nut drives the leading screws on the left pliers body and the right pliers body to stretch out simultaneously, so that the pliers handle is opened outwards and the pliers tip is also opened outwards through the hinge connection.

Preferably, the lead screws on the left caliper body and the right caliper body are respectively close to the joints of the left caliper body and the right caliper body.

Due to the application of the above-mentioned technical solution, the utility model has the following advantages compared with the prior art:

The microsurgical point-shaped spreader of the utility model exposes the wound surface through the opening of the jaws, and the tissue damage is small when the jaws are opened, the size is convenient to control, the adjustment is convenient, safe and reliable, thereby saving operation time.

Description of drawings

Below in conjunction with accompanying drawing, technical scheme of the utility model is further described:

Accompanying drawing 1 is the structure schematic diagram of microsurgery point shape spread forceps described in the utility model;

Among them: 1. Left pliers body; 2. Right pliers body; 3. Pliers tip; 4. Pliers handle; 5. Lead screw; 6. Adjusting nut.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Accompanying drawing 1 is microsurgery point-like spreading forceps described in the utility model, comprises left forceps body 1, right forceps body 2; Said left forceps body 1 and right forceps body 2 are intersected and hingedly connected; The 3 pincer tips of the pliers body 1 and the right pliers body 2 are respectively provided with outwardly curved arc-shaped traction hooks, which are convenient for opening and exposing the wound surface; Rotatable lead screws 5 are respectively arranged at the positions; the lead screws 5 on the left pliers body 1 and the right pliers body 2 are connected by an adjusting nut 6; during work, turning the adjusting nut 6 drives the left pliers body 1 and the right pliers body The lead screw 5 on the body 2 protrudes outwards at the same time, so that the forceps handle 4 is opened outwards and the forceps tip 3 is also opened outwards through the hinge connection, exposing the wound surface and facilitating the operation.

Due to the application of the above-mentioned technical solution, the utility model has the following advantages compared with the prior art:

The microsurgical point-shaped spreader of the utility model exposes the wound surface through the opening of the jaws, and the tissue damage is small when the jaws are opened, the size is convenient to control, the adjustment is convenient, safe and reliable, thereby saving operation time.

The above are only specific application examples of the utility model, and do not constitute any limitation to the protection scope of the utility model. All technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the utility model.
