Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a watershed-type temporary blood vessel blocking forceps. Background Art
[0002] Temporary vascular blocking forceps, commonly known as "pug forceps", are used to clamp blood vessels during surgery to temporarily stop bleeding. Current temporary vascular blocking forceps directly use an ordinary forceps to clamp the clamp used to clamp the blood vessel. When in use, the forceps need to be held at a certain contact angle and orientation to make the inner side of the forceps head at the front end contact with the outer side of the clamp, so that the clamp can be clamped by the forceps. This type of temporary vascular blocking forceps cannot clamp, release, and clamp at multiple angles during surgery, and is not very convenient to use, especially for the blocking of basin-type blood vessels. Basin-type blood vessels are blood vessels in the blood basin formed by extending from the main arteriovenous trunk along the branch blood vessels. The blood vessels are small and often distributed on the inside of the organ. Sometimes the line of sight is poor. The current temporary vascular blocking forceps are even more inconvenient to use in this type of surgery. Utility Model Content
[0003] The utility model aims to provide a basin-type temporary blood vessel blocking forceps, which can realize the multi-angle and flexible clamping, application and clamping of the clamps for temporarily blocking the basin-type blood vessels during surgery.
[0004] In order to achieve the above objectives, the present invention adopts the following technical solutions:
[0005] Provided are a basin-type temporary vascular blocking forceps, comprising a forceps and a clamp, wherein the front end of the forceps comprises a first forceps head and a second forceps head that can be opened and closed, wherein the inner sides of the first forceps head and the second forceps head are respectively provided with a hemispherical first groove and a second groove, and the clamp comprises a first clamp arm and a second clamp arm that can be opened and closed, wherein the outer sides of the first clamp arm and the second clamp arm are respectively provided with a hemispherical first protrusion and a second protrusion corresponding to the first groove and the second groove; or a hemispherical protrusion is respectively provided on the inner sides of the first forceps head and the second forceps head, and a hemispherical groove is respectively provided on the outer sides of the first clamp arm and the second clamp arm.
[0006] Preferably, the rear halves of the first clamping arm and the second clamping arm of the clamp are spaced apart, the rear ends are connected as a whole to form a connecting portion, and are cross-arranged in the middle part, the front half is in a closed state, and the first protrusion and the second protrusion are arranged on the rear side of the intersection of the first clamping arm and the second clamping arm. When the first protrusion and the second protrusion on the first clamping arm and the second clamping arm are clamped by the pliers, the first clamping arm and the second clamping arm are opened at the front end.
[0007] Preferably, the pliers include a first pliers rod and a second pliers rod, the first pliers head is a movable pliers head arranged at the front end of the first pliers rod, and the rear end of the first pliers head is hinged to the front end of the first pliers rod; the second pliers head is a fixed pliers head located at the front end of the second pliers rod; the rear part of the first pliers rod is a fixed handle, and a movable handle is provided at the rear end of the second pliers rod, and a buckling rod is provided on the inner side of the fixed handle and the movable handle respectively, and the buckling rod is provided with buckling teeth; a push rod is provided in the first pliers rod, the front end of the push rod is hinged to the rear end of the first pliers head, and the rear end of the push rod is hinged to the front end of the movable handle, so that operating the movable handle can drive the first pliers head to open and close through the push rod.
[0008] Preferably, the inner sides of the first clamping arm and the front half of the second clamping arm of the clamp are respectively provided with clamping teeth.
[0009] Compared to the prior art, the present invention offers the following advantages: The watershed-type temporary vascular occlusion forceps utilize hemispherical first and second protrusions on the outer sides of the first and second clamp arms, respectively, and first and second grooves on the inner sides of the first and second clamp heads, respectively. When the forceps grasp the clamp, the first and second grooves on the inner sides of the first and second clamp heads allow the forceps to grip the first and second protrusions at various angles, providing greater operational flexibility. Compared to conventional vascular occlusion forceps, the outer side of the clamp and the clamp applicator head exhibit matching hemispherical structures, enabling multi-angle clamping, placement, and removal during surgery, even enabling semi-blind operation in poor visibility, significantly improving surgical efficiency and safety. Conventional vascular occlusion forceps, on the other hand, can only operate at a single angle and are difficult to adapt to. Furthermore, this structure allows the forceps to precisely grasp the clamp, resulting in a compact clamp with an overall size only one-third that of conventional clamps, facilitating the occlusion of small watershed-type vessels.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] In one embodiment, a watershed type vascular temporary blocking clamp is provided, such as Figure 1-8 As shown, the basin-type temporary vascular blocking forceps includes a forceps 1 and a clamp 2. The forceps 1 is used to facilitate the doctor to operate the clamp 2 to clamp the blood vessel during surgery. During surgery, the doctor clamps the clamp 2 with the forceps 1 so that the clamp 2 opens and clamps the blood vessel. Then the forceps 1 can be loosened and the clamp 2 is released. At this time, the clamp 2 is clamped on the blood vessel to stop bleeding. When the clamp 2 needs to be removed, the doctor clamps the clamp 2 again with the forceps 1 so that the clamp 2 opens and is removed from the blood vessel.
[0022] The front end of the pliers 1 has a first pliers head 11 and a second pliers head 12 that can be opened and closed. The doctor can operate the first pliers head 11 and the second pliers head 12 to open or close using the handle on the back side of the pliers 1. The inner sides of the first pliers head 11 and the second pliers head 12 are respectively provided with a hemispherical first groove 13 and a second groove 14; the clamp 2 includes a first clamp arm 21 and a second clamp arm 22 that can be opened and closed. When the clamp 2 is not under pressure, the front half of the first clamp arm 21 and the second clamp arm 22 are clamped. When the pliers 1 is used to clamp the clamp 2, the front half of the first clamp arm 21 and the second clamp arm 22 can be opened. The outer sides of the first clamp arm 21 and the second clamp arm 22 are respectively provided with a hemispherical first protrusion 23 and a second protrusion 24 corresponding to the first groove 13 and the second groove 14.
[0023] When the doctor clamps the clamp 2 with the pliers 1, the first grooves 13 and the second grooves 14 on the inner sides of the first pliers head 11 and the second pliers head 12 respectively match the first protrusions 23 and the second protrusions 24 on the outer sides of the first clamp arm 21 and the second clamp arm 22, and then the first pliers head 11 and the second pliers head 12 are controlled to close by the handle on the rear side of the pliers 1, so that the first pliers head 11 and the second pliers head 12 can clamp the first protrusions 23 and the second protrusions 24 of the first clamp arm 21 and the second clamp arm 22, so that the front half of the clamp 2 is opened; when the first pliers head 11 and the second pliers head 12 are controlled to open by the handle on the rear side of the pliers 1, the first grooves 13 and the second grooves 14 on the inner sides of the first pliers head 11 and the second pliers head 12 are respectively disengaged from the first protrusions 23 and the second protrusions 24 on the outer sides of the first clamp arm 21 and the second clamp arm 22, and the clamp 2 will be detached from the pliers 1, and the front half of the first clamp arm 21 and the second clamp arm 22 of the clamp 2 is restored to the closed state.
[0024] In other embodiments, hemispherical protrusions may be provided on the inner sides of the first clamp head and the second clamp head, respectively, and hemispherical grooves may be provided on the outer sides of the first clamp arm and the second clamp arm, respectively.
[0025] The basin-type temporary vascular occlusion forceps are provided with a hemispherical first protrusion 23 and a second protrusion 24 on the outside of the first clamp arm 21 and the second clamp arm 22 of the clamp 2, and a first groove 13 and a second groove 14 are provided on the inside of the first clamp head 11 and the second clamp head 12 of the forceps 1. When the clamp 2 is clamped by the forceps 1, the forceps 1 can clamp the first protrusion 23 and the second protrusion 24 on the clamp 2 at different angles through the first groove 13 and the second groove 14 on the inside of the first clamp head 11 and the second clamp head 12, making the operation more flexible. Compared with the traditional vascular occlusion clamp device (commonly known as "pug clamp"), the advantages are as follows: 1. The outer surface of the clamp 2 and the clamp head of the clamping forceps 1 present a matching hemispherical structure, which can realize multi-angle clamping, application, clamping and other operations during surgery, and even realize semi-blind operation when the vision is poor, thereby achieving a qualitative improvement in the efficiency and safety of the surgery. Traditional vascular occlusion clamp devices can only operate at a single angle and are difficult to adapt to poor angles. 2. This structure enables forceps 1 to precisely grasp clip 2, allowing clip 2 to be made compact. The overall size of clip 2 is only one-third the size of traditional clips, making it easier to occlude small, basin-type blood vessels. Basin-type blood vessels refer to blood vessels in the blood flow basin formed by branches extending from the main artery and vein.
[0026] Furthermore, in another embodiment, Figure 6 As shown, Figure 6 The clamp 2 is in its original, unclamped state. The rear halves of the first and second arms 21, 22 of the clamp 2 are spaced apart and connected at their rear ends to form a connecting portion 25. This allows the rear halves of the first and second arms 21, 22 to elastically deform when the clamp 2 is clamped by the forceps 1. The middle portion of the clamp 2 is arranged crosswise, with the front half in a closed state. The first and second protrusions 23, 24 are located behind the intersection of the first and second arms 21, 22. When the forceps 1 is clamped, the first and second arms 21, 22 open in their front halves. When the forceps 1 is released, the rear halves of the first and second arms 21, 22 return to their original positions, while the first and second arms 21, 22 return to their closed positions in their front halves. The clip 2 is provided with notches in the middle of the first clamping arm 21 and the second clamping arm 22, so as to facilitate the cross arrangement of the two arms.
[0027] Furthermore, in another embodiment, Figure 1-5 As shown, the forceps 1 in the basin-type temporary vascular occlusion forceps include a first forceps rod 15 and a second forceps rod 16, which are fixedly connected together side by side. The first forceps head 11 is a movable forceps head arranged at the front end of the first forceps rod 15, and the rear end of the first forceps head is hinged to the front end of the first forceps rod 1. Specifically, Figure 5 As shown, the rear end of the first pliers head 11 is provided with two hinge holes, wherein the hinge hole on the lower left side is hinged in the front end connecting groove of the first pliers rod 15; the second pliers head 12 is a fixed pliers head located at the front end of the second pliers rod 16, and the second pliers head 12 can be fixed at the front end of the second pliers rod 16, or the second pliers head is integrally arranged at the front end of the second pliers rod; the rear part of the first pliers rod 15 is a fixed handle 17, and in this embodiment, the fixed handle 17 is integrally formed with the first pliers rod 15; and a movable handle 18 is provided at the rear end of the second pliers rod 16, combined with Figure 4 As shown, the front end of the movable handle 18 is slightly bent upward, and the front end of the movable handle 18 is also provided with two hinge holes, of which the lower left hinge hole is hinged to the rear end of the second clamp rod 16; the inner sides of the fixed handle 17 and the movable handle 18 are respectively provided with a buckle rod 19, and the buckle rod 19 is provided with a buckle tooth. When the fixed handle 17 and the movable handle 18 are pinched together, and the buckle teeth on the buckle rod 19 of the two are buckled together, the fixed handle 17 and the movable handle 18 can maintain the pinched state, and the first pliers head 11 and the second pliers head 12 at the front end can also maintain the closed state; as shown Figure 4 As shown, a push rod 3 is provided in the first pliers rod 15. The interior of the first pliers rod 15 is hollow. The push rod 3 passes through the first pliers rod 15. The front end of the push rod 3 is hinged to a hinge hole on the upper right side of the rear end of the first pliers head 11. The rear end of the push rod 3 is hinged to a hinge hole on the upper right side of the front end of the movable handle 18, so that the operation of the movable handle 18 can drive the first pliers head 11 to open and close through the push rod 3.
[0028] In other embodiments, the forceps in the basin-type temporary vascular occlusion forceps can also use other types of forceps, such as scissor-shaped forceps, as long as corresponding grooves or protrusions are set on the two front end forceps to enable the clamps to be clamped.
[0029] In addition, in one embodiment, clamp teeth are provided on the inner sides of the front halves of the first clamp arm 21 and the second clamp arm 22 of the clamp 2. The clamp teeth here are longitudinal strip teeth so as to be able to clamp the blood vessels. Transverse teeth may also be used in other embodiments.
