Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a protective sleeve for the end of a detachable vascular clamp. Background Technology

[0002] Vascular forceps are mainly used to clamp blood vessels or bleeding points, also known as hemostatic forceps. They come in different shapes and sizes depending on the application. Conventional vascular forceps are usually made of metal, and the head of the forceps is serrated to clamp and seal blood vessels or bleeding points.

[0003] The utility model patent with announcement number CN2796652Y discloses a cannula-type vascular clamp. A suitable silicone tube is fitted onto the two forearms of the vascular clamp. The vascular clamp with the silicone tube is then used to clamp the plastic tube. The teeth of the vascular clamp will not damage the plastic tube, thus avoiding the rupture and breakage of the plastic tube.

[0004] However, the aforementioned cannulated vascular clamps still have the following problems during use: Although a silicone tube is used to cover the clamp head to reduce damage, the cannula does not have a toothed structure, resulting in poor clamping effect on blood vessels and bleeding points, which makes it easy to slip off. At the same time, the end of the vascular clamp is designed to be narrow at the top and wide at the bottom, and the cannula is prone to falling off during repeated contact, which affects hemostasis and the effectiveness of use.

[0005] Therefore, we propose an anti-dislodgement end protector for vascular clamps to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an anti-dislodgement end protector for vascular clamps. This addresses the problem that existing vascular clamps use silicone tubes fitted over the clamp head to reduce damage, but these tubes lack toothed structures, resulting in poor clamping effect on blood vessels and bleeding points, making them prone to slippage. Additionally, the clamp head has a narrow top and wide bottom design, which makes the tube prone to detachment during repeated contact, thus affecting hemostasis and overall effectiveness.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a protective sleeve for the end of a vascular clamp that prevents detachment, comprising a vascular clamp body, and a main movable rod and a secondary movable rod that make up the vascular clamp body;

[0008] It also includes: a main clamp head and a secondary clamp head, which are respectively fixedly installed at the top end of the main movable rod and the top end of the secondary movable rod;

[0012] Preferably, the protection mechanism comprises a strip-shaped protrusion for increasing friction, and the strip-shaped protrusion is fixedly arranged at the inner side of the protection sleeve body on the left and right sides, and the protection sleeve bodies on the left and right sides are sleeved on the outside of the main jaw and the auxiliary jaw through the installation cavities formed in the inside.

[0013] Preferably, the protection sleeve body of the protection mechanism is made of polyurethane rubber material, and the protection sleeve body is in a flexible structure for protecting the main jaw and the auxiliary jaw, preventing damage to blood vessels and tissues during the operation.

[0014] Preferably, the protection mechanism comprises a positioning sleeve ring, and the positioning sleeve ring is detachably installed in the inside of the finger ring buckles on the left and right sides, and the flexibility of the finger part of the doctor is improved through the positioning sleeve ring, reducing the wear between the finger part and the finger ring buckle.

[0015] Preferably, the protection mechanism comprises an elastic connecting rod, and the outer end of the elastic connecting rod connects the protection sleeve body and the positioning sleeve ring, respectively, ensuring the tightness of the protection sleeve body in use.

[0016] Preferably, the middle part of the elastic connecting rod is provided with a positioning connecting ring, and the positioning connecting ring is detachably installed on the outer wall of the lower end of the main movable rod and the auxiliary movable rod, so as to position the elastic connecting rod through the positioning connecting ring.

[0017] Compared with the prior art, the end head protection sleeve of the blood vessel forceps has the following beneficial effects: the flexible material of the protection sleeve body and the strip-shaped protrusion can replace the contact of the jaw with the blood vessels and the bleeding site, reduce the wear of the blood vessels and the bleeding points, the detachable sleeve ring in the inside of the finger ring buckle contacts the finger part of the doctor, reducing the damage caused by the holding friction, the elastic connecting rod ensures the tightness of the installation of the protection sleeve body and the positioning sleeve ring, avoiding slipping in use, and the specific contents are as follows:

[0018] 1. The protective sleeve body is sleeved on the outer end of the main jaw and the auxiliary jaw through the internal mounting cavity, and the strip-shaped protrusion arranged at the inner end of the protective sleeve body can increase the stability when contacting the blood vessels and bleeding points, and the flexible material of the protective sleeve body can avoid hard contact with the blood vessels and bleeding points, thereby reducing the abrasion of the blood vessels and bleeding points.

[0019] Further, the main jaw and the auxiliary jaw are frictionally attached to the inner wall of the protective sleeve body through the concave shape of the main jaw and the auxiliary jaw, thereby assisting the tightness of the protective sleeve body and the connection thereof, and avoiding slipping during use.

[0020] 2. The positioning ring is detachably mounted in the inner part of the finger ring buckle, the positioning ring replaces the finger ring buckle to contact the finger part of the doctor, and the relatively wide positioning ring can increase the contact area of the finger and reduce the damage caused by continuous friction during gripping.

[0021] Meanwhile, the elastic connecting rod connects the positioning ring and the protective sleeve body, and is mounted below the left and right main movable rods and auxiliary movable rods through the positioning connecting ring, so as to ensure the adhesion of the connection between the blood vessel forceps body and the protective sleeve body, and avoid falling off during continuous contact and friction.
