Description

Technical Field

[0001] The utility model relates to a separation forceps for laparoscopes, belonging to the technical field of medical instruments. Background Art

[0002] With the continuous advancement of medical technology, people's expectations for the effectiveness and quality of medical services are becoming increasingly higher. Minimally invasive laparoscopic surgery will become a key area of ​​surgical intervention. Single-port thoracoscopic surgery is currently widely used to treat chest diseases. However, due to the small single incision, it not only requires higher technical skills of the surgeon, but also increasingly demanding requirements for the equipment.

[0003] However, existing separation forceps often have a large number of angular structures on the head or are bulky, which can easily be restrained by the adhesive tissue in the blood vessels when passing through the human body. The forceps can only be forced through by applying sufficient external force, which is inefficient and inevitably causes blood vessel damage, leading to postoperative infection and other situations. Therefore, there is an urgent need for a separation forceps that can improve the efficiency of separation forceps entering human blood vessels and prevent damage to the blood vessels. Utility Model Content

[0004] The technical problem to be solved by the present invention is how to solve the problem that the clamp head structure of the existing separation forceps has many edges and corners or is large in size, which makes it easy to be restrained by the adhesive tissue in the blood vessels when passing through the human blood vessels, thereby resulting in low entry efficiency and causing blood vessel damage.

[0005] In order to solve the above technical problems, the utility model provides a laparoscopic separation forceps, which can separate sticky tissues as much as possible while entering human blood vessels, thereby improving entry efficiency and reducing blood vessel damage.

[0006] To achieve the above technical objectives and effects, this application is implemented through the following technical solutions:

[0007] A separation forceps for laparoscope, characterized in that it includes a forceps body one and a forceps body two, the forceps body one and the forceps body two are hinged, and the ends of the forceps body one and the forceps body two are both provided with handles, and the ends of the forceps body one and the forceps body two facing away from the handle are bent in the same direction to form an arc-shaped portion, and the end of the arc-shaped portion on the forceps body one facing away from the forceps body one is provided with a forceps head one, and the end of the arc-shaped portion on the forceps body two facing away from the forceps body two is provided with a forceps head two, the forceps head one and the forceps head two are both snake-head-shaped, and the sides of the forceps head one and the forceps head two facing away from each other are both arc surfaces.

[0008] Preferably, the size of the head ends of the first and second pliers heads is between 3 cm and 4 cm.

[0009] Preferably, the straight-line distance between the two end points of the curved portion of the first and second clamp bodies is between 10 cm and 25 cm.

[0010] Preferably, the head ends of the first and second clamp heads are both configured as rounded portions.

[0011] Preferably, the first clamp head and the second clamp head are both solid structures.

[0012] Preferably, mutually engaging non-damaging teeth are provided on opposite sides of the first and second pliers heads.

[0013] The utility model provides a laparoscope separation forceps, which has the following advantages:

[0014] 1. The laparoscopic separation forceps of the present invention are designed to have the first and second heads of the separation forceps in the shape of a snake head, and the head ends are provided with rounded portions. The rounded heads can facilitate the entry of the forceps into human blood vessels. When the forceps enter the human blood vessels, the narrow portion of the snake head can be used to pre-enter the blood vessels to separate and evacuate adhered tissues, and then gradually transition to the wider portion of the snake head to gradually open the blood vessels for easier entry of the separation forceps. This improves the efficiency of the separation forceps entering the human blood vessels while preventing damage to the blood vessels.

[0015] 2. The laparoscope separation forceps of the present invention have one end of the forceps body 1 and the other end of the forceps body 2 provided with the forceps head as an arc-shaped portion, which can further improve the efficiency of the forceps body entering the human body and reduce damage, while facilitating the doctor's clamping operation.

[0021] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this utility model, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technical personnel in this field without making creative efforts are within the scope of protection of this utility model.

[0022] Reference Figure 1-Figure 3 A laparoscope separation forceps, characterized in that it includes a forceps body 1 and a forceps body 2, the forceps body 1 and the forceps body 2 are hinged, and handles 3 are integrally formed on the two opposite outer walls of the same end of the forceps body 1 and the forceps body 2, and the ends of the forceps body 1 and the forceps body 2 facing away from the handle 3 are bent in the same direction to form an arc portion 4, and the straight-line distance between the two end points of the arc portion 4 is set to H, and the size of H is between 10cm and 25cm. The end of the arc portion 4 on the forceps body 1 facing away from the forceps body 1 is integrally formed with a forceps head 1, and the end of the arc portion 4 on the forceps body 2 facing away from the forceps body 2 is integrally formed with a forceps head 2 6, both the forceps head 1 5 and the forceps head 2 6 are snake-head shaped, and the sides of the forceps head 1 5 and the forceps head 2 6 facing away from each other are both arc surfaces.

[0023] Furthermore, the size of the head ends of the forceps head 1 5 and the forceps head 2 6 is between 3 cm and 4 cm, and the head ends of the forceps head 1 5 and the forceps head 2 6 are both set as chamfered parts 7, making the head ends of the forceps rounded and easy to enter the human blood vessels.

[0024] Furthermore, both the first clamp head 5 and the second clamp head 6 are solid structures to reduce the possibility of the clamp head end being hooked by the adhesive tissue in the human blood vessel when entering the blood vessel, thereby pulling the tissue during the entry process and causing blood vessel damage.

[0025] Furthermore, mutually meshing non-damaging teeth 8 are integrally formed on the opposite sides of the forceps head 1 5 and the forceps head 2 6. The arrangement of the non-damaging teeth 8 on the forceps head 1 5 and the forceps head 2 6 improves the anti-slip property of the separation forceps during the clamping process, thereby improving the efficiency of the operation.

[0026] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form or substance. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the present invention, and these improvements and supplements should also be considered as the scope of protection of the present invention.
