Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a water-bag type blood vessel blocking forceps. Background Art

[0002] Temporary occlusion of blood vessels is an important operation in surgery, which can help the surgeon control bleeding when operating on a certain organ and ensure a clear surgical field. However, if the ischemia caused by vascular occlusion reaches a certain time, it will cause tissue cells to be damaged by hypoxia, and may cause ischemia-reperfusion injury after the blood supply is restored, which may cause adverse clinical consequences such as inflammatory factor storm. In addition, existing evidence shows that a single long-term blood supply interruption causes much more damage to tissues than multiple short-term blood supply interruptions. Therefore, if the blood vessels are not completely blocked for a long time, but partially blocked or intermittently blocked, the ischemic damage to the organ can be directly reduced at the cost of a small amount of bleeding in the surgical field, thereby protecting the organ function in the long run.

[0003] The vascular blockers currently used in clinical practice are usually rigid clamps, which cause certain mechanical damage to the outer wall of the blood vessel. Moreover, they completely clamp the blood vessel to be blocked and cannot adjust the degree of blood vessel blockage. If you want to perform intermittent blockage, you need to repeatedly place and remove the blocking clamp. This repeated movement and friction around the target blood vessel may cause blood vessel rupture and severe bleeding. This bleeding may lead to serious adverse consequences such as conversion of laparoscopic surgery to open surgery, removal of organs that have lost their blood supply, and hemorrhagic shock. In addition, if you want to perform intermittent blockage during laparoscopic surgery, you also need to use a clamp to operate, which is cumbersome and time-consuming. Utility Model Content

[0004] The utility model provides a water-bag type vascular blocking clamp to solve the technical problems that the existing vascular blocking clamp cannot adjust the degree of vascular blocking and needs to be repeatedly placed and removed when performing intermittent blocking, which increases the risk of vascular rupture.

[0005] The utility model is realized by adopting the following technical solutions.

[0006] A water-bag-type vascular blocking forceps comprises a main body formed by hingedly connecting a first clamp body and a second clamp body, wherein the first clamp body and the second clamp body have the same structure, the tails of the first clamp body and the second clamp body are connected by a spring, the edges on both sides of the head of the first clamp body and the second clamp body are bent inward to form outer baffles, and a blocking plate is provided between the outer baffles on both sides, and the blocking plate is connected to the opposite surfaces of the first clamp body and the second clamp body; a water bag is embedded in the main body, the water bag comprises a main bag body, the upper part of the main bag body is connected to four sub-bag bodies, and the four sub-bag bodies are respectively placed between the blocking plates and the outer baffles of the first clamp body and the second clamp body.

[0007] Furthermore, an arc-shaped support plate is connected to the upper middle portion of the opposing surfaces of the first pliers body and the second pliers body.

[0008] Furthermore, a connecting portion is formed in the middle of the first caliper body and the second caliper body, and a hinge shaft passes through the connecting portion of the first caliper body and the second caliper body to hinge the two.

[0009] Furthermore, the main bag body is provided with a water inlet and outlet, which are connected to the connecting joint.

[0010] This application has the following beneficial effects.

[0011] This new water-filled vascular occlusion forceps can adjust the degree of occlusion on the target vessel by adjusting the expansion of the water bag. This facilitates activating and deactivating the occlusion and adjusting the degree of occlusion during laparoscopic surgery, enabling complete, partial, and intermittent occlusion of organ blood supply. Furthermore, because the water bag compresses rather than clamps the blood vessels, the risk of vascular damage is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1-8 As shown, a water-bag type vascular blocking forceps comprises a body 1 and a water bag 3 , wherein the water bag 3 is movably embedded in the body 1 .

[0023] Specifically, the main body 1 includes a first pliers body 101 and a second pliers body 102 . The first pliers body 101 and the second pliers body 102 have the same structure. The structures of the two pliers bodies will be further described below taking the first pliers body 101 as an example.

[0024] The first clamp body 101 includes a base plate 107. The edges of the base plate 107 are bent toward the side of the second clamp body 102 to form an outer baffle 104. A blocking plate 105 is provided on the side of the base plate 107 near the second clamp body 102. The blocking plate 105 is positioned between the outer baffles 104 on both sides. The outer baffles 104 on both sides and the central blocking plate 105 together form two sub-capsule accommodating spaces. The height of the blocking plate 105 is greater than that of the outer baffle 104. When the clamp bodies are closed, the two blocking plates 105 come into contact to completely block the blood vessel 5.

[0025] An arc-shaped support plate 106 is provided below the blocking plate 105 of the present invention, one end of the support plate 106 is fixed to a side of the base plate 107 close to the second clamp body 102, and the other end extends toward the second clamp body 102. The support plate 106 supports the water bag 3 to prevent the water bag from falling out of the body 1.

[0026] The base plate 107 of the first jaw 101 extends from both sides of the middle portion toward the second jaw 102 to form a connecting portion, with a hinge hole formed at the end of the connecting portion. The hinge shaft 103 passes through the hinge holes of the first jaw 101 and the second jaw 102, thereby hingedly connecting the first jaw 101 and the second jaw 102. After the first jaw 101 and the second jaw 102 are hinged, the main body 1 forms an embedding hole 4 for the water bag between the lower end of the blocking plate 105 and the hinge shaft 103.

[0027] A spring 2 is connected between the tails of the first caliper body 101 and the second caliper body 102 . Both ends of the spring 2 are fixed on opposite surfaces of the base plates 107 of the first caliper body 101 and the second caliper body 102 . The spring 2 is used to restore the caliper bodies to a closed state.

[0028] The water bladder 3 comprises a main bladder body 302, the upper portion of which communicates with four elongated sub-bladder bodies 301. The four sub-bladder bodies 301 are respectively inserted into the four sub-bladder receiving spaces formed by the first clamp body 101 and the second clamp body 102. To place the water bladder 3 within the main body 1, the rear portion of the main body 1 is pinched to open the top portion. The main bladder body 302 is then inserted into the main body 1 through the insertion hole 4 and placed on the support plate 106. The four sub-bladder bodies 301 are then inserted into the four sub-bladder receiving spaces. Finally, the top portion of the main body 1 is closed to complete the installation of the water bladder 3.

[0029] The water bladder 3 of the present invention is made of a material with excellent elasticity and toughness. Once filled to a certain expansion limit, the surgical suction perfusion device cannot continue to inject water using conventional pressure. When the liquid in the water bladder 3 of the present invention is completely absorbed, the blocking plates 105 of the first and second clamp bodies 101, 102 are pressed together by the spring 2, consistent with conventional blocking clamps, achieving complete blockage of the blood vessel. As the water content of the water bladder 3 increases, the water bladder 3 gradually fills, and the target vessel transitions from a completely blocked state under clamping to a compressed state of the water bladder. Because the water bladder 3 can wrap around the outer surface of the vessel 5, the contact area is increased, reducing the pressure outside the vessel 5, thereby achieving a partial blockage effect. When the water bladder 3 reaches maximum filling, the pressure on the vessel 5 is minimized, and effective blood perfusion can be restored to the organ. Based on the above, the present invention changes the degree of blockage of the target vessel by adjusting the expansion of the water bladder, and can achieve intermittent blockage of the vessel without repeatedly placing and removing the blocking clamp.

[0030] The main bladder body 302 of the present application has water inlets and outlets formed thereon, which are connected to the connection joint 303 , which is connected to the suction and irrigation device, respectively achieving the effects of contracting and filling the water bladder 3 through suction and irrigation functions.

[0031] In practical application, taking laparoscopic surgery as an example: when the water bladder 3 is empty or nearly empty, the present invention is placed on the target blood vessel using a clamp. At this point, the two blocking plates 105 clamp the blood vessel 5, and the pressure on the blood vessel 5 is maximized, achieving a complete blockade. When the patient's vital signs are stable and the bleeding is expected to be controllable, to reduce organ ischemia time, I. partial blockage can be considered: connect the suction perfusion device to the connector 303, and inject physiological saline into the water bladder 3 to bring the water bladder 3 to a semi-filled state. At this time, the surgical field is slightly bleeding, and with the help of the suction device, the surgical field can be kept clear and the surgical procedure can be completed; II. After sufficient hemostasis is achieved in the surgical field using methods such as electrocoagulation and spray coagulation, intermittent blockage is switched: water is injected into the water bladder 3 using the above method to bring the water bladder 3 to a fully filled state. At this point, blood supply to the organ is restored, and since the cross-section of the blood vessels in the surgical area has been sealed, the surgical field is in a state of no bleeding or minimal bleeding. After the organ blood circulation has been completed for a certain period of time, the liquid in the water bag 3 is sucked out by the suction perfusion device, the blood vessel is switched to the blocked state and the operation is completed. After the operation on the organ is completed, the tail of the body 1 is clamped and removed using a clamp.

[0032] The blocking forceps of the present application can be designed in different models according to different target blood vessels (such as renal artery, hepatic pedicle, etc.), so as to ensure that the water bag 3 can achieve complete blocking, partial blocking and blood circulation restoration effects in the empty state, semi-filled state and fully filled state respectively.

[0033] This innovative water-filled vascular blocking clamp can adjust the degree of blood vessel blockage by adjusting the filling level of the water bag, supporting partial or intermittent blockage of organ blood supply. This new clamp can assist the surgeon in quickly and easily blocking and opening the target vessel, especially during laparoscopic surgery, where placement and removal of conventional blocking clamps is time-consuming.

[0034] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
