Description

A kind of percutaneous channel expansion forceps

technical field

The utility model relates to the field of medical tools, in particular to a percutaneous channel expansion forceps.

Background technique

In clinical medicine, percutaneous channel expansion is often required for retroperitoneal laparoscopic surgery, transabdominal laparoscopic surgery, and thoracoscopic surgery.

There are mainly two kinds of expansion forceps used clinically in the existing surgery: straight vascular forceps and curved vascular forceps. Surgeons can use these two forceps to perform blunt tissue expansion to dilate percutaneous channels. When adopting above-mentioned two kinds of expansion forceps, at first use forceps point to pierce the subcutaneous of incision, then stretch out subcutaneous tissue, when the depth of needing expansion is relatively shallow, it can meet the requirement of use. However, when the depth of expansion is deep, it is often necessary to stand up the pliers for operation. At this time, the operator's hand holding the pliers handle needs to be suspended above the channel cutout, which increases the difficulty of operation and is inconvenient to use. . Moreover, the operator's hand easily blocks the space above the channel incision, making it difficult for the operator to observe the situation of the expanded part of the channel with eyes.

It is not difficult to see that there are certain defects in the prior art.

Utility model content

The technical problem to be solved by the utility model is to provide a percutaneous channel expansion forceps, which is convenient for percutaneous channel expansion.

In order to achieve the above object, the utility model adopts the following technical solutions:

A kind of percutaneous channel expansion forceps, comprising two symmetrical forceps bodies, the forceps body includes a handle part, a hinge part and a working end; the handle part is located at the rear end of the forceps body, and the end part of the handle part is a hollow shape matching with human fingers Ring shape; the hinge part is located in the middle of the pliers body, and the two pliers bodies are hinged together through the hinge part with pins; the working end is located at the front end of the pliers body, and the working end is set at right angles to the handle part, and the working end is pointed and tapered. Root thickly conical.

Further, the length of the working end of the pliers is 3-10 cm.

A kind of percutaneous channel expansion forceps provided by the utility model has the following advantages:

The working end is set at a right angle, and the operator does not need to lift his hand in the air when expanding the percutaneous channel, which makes the operation more convenient;

The operator's hands will not block the view of the channel cutout, which is convenient for the operator to observe;

Reduce the difficulty of operation and reduce the damage to patients during clinical operations.

detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model and the accompanying drawings. It should be noted that the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Example

Please refer to Fig. 1, the present embodiment discloses a kind of percutaneous channel expansion forceps, which comprises two structurally symmetrical forceps bodies, the forceps body includes a handle part 1, a hinged part 2 and a working end 3; the handle part 1 is located at the rear end of the forceps body , the end of the handle part 1 is a hollow ring that fits with the fingers of the human body; the hinge part 2 is located in the middle of the pliers body, and the two pliers bodies are hinged together through the hinge part 2 with pins; the working end 3 is located at the front end of the pliers body , the working end 3 is arranged at right angles to the handle portion 1, and the working end 3 is tapered with a tapered tip and a thick root. Preferably, the length of the working end 3 of the pliers is 3-10 cm.

In the prior art, there is no dedicated percutaneous channel expansion tool, and medical personnel usually use vascular clamps as an alternative tool. However, the structure of the vascular clamp is not conducive to the operation of percutaneous channel expansion. The vascular clamp is generally straight or curved, which causes the operator to raise his hand to fit the incision when performing percutaneous channel expansion, which increases the difficulty of operation. In addition, it is easy to obstruct the line of sight, making it difficult for the operator to observe the situation of the incision, and even cause additional damage to the patient in severe cases.

The working end 3 of the percutaneous channel expansion forceps of the utility model adopts a right-angle design, and the tip of the working end 3 is relatively tapered and the root is relatively thick, so that it is convenient to enter the incision. During the process of expanding the percutaneous channel, the working end 3 penetrates through the incision of the skin, and the working end 3 is vertically inserted into the tissue (usually subcutaneous tissue, subcutaneous fat, body wall muscle layer, etc.), and then the operator controls the handle part 1 Stretch to expand. During this process, the operator's hand holds the handle part 1, and the wrist is placed naturally and comfortably, and the expansion process is easier to control, which greatly reduces the difficulty of clinical operations. At the same time, the operator's hand is located on the side of the patient's expansion channel, which will not hinder the line of sight of the expansion channel, so the operator can conveniently observe the situation in the expanded channel cavity from above the channel opening, and identify muscles, tissues and deep organs. Viscera monitors the expansion process, improves the operation accuracy of percutaneous channel expansion, and also greatly reduces additional damage to the patient.

The utility model provides a kind of percutaneous channel expansion forceps, the working end 3 of which is arranged at a right angle, and the operator's hand does not need to be lifted in the air when performing percutaneous channel expansion, and the operation is more convenient and comfortable. Moreover, the operator's hands will not block the sight line of the channel incision, which is convenient for the operator to observe, improves the accuracy of the operation, and further reduces the damage to the patient during clinical operations.

The above-mentioned embodiment only expresses one implementation mode of the utility model, and its description is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the scope of protection of the utility model patent should be based on the appended claims.
