Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an adjustable intra-abdominal compression hemostasis device. Background Technology

[0002] During clinical diagnosis and treatment, patients may experience massive bleeding in the abdominal organs. If the bleeding is not stopped in time, it will seriously endanger the patient's life and health. Currently, compression hemostasis is commonly used in clinical practice. For example, an intra-abdominal compression hemostasis device with adjustable shape and pressure is disclosed in CN219397426U. This device is equipped with a detachable external hemostatic layer and an internal expansion structure. After the external hemostatic layer is aligned with the bleeding site, the internal expansion structure is expanded by an air pump to compress the wound and achieve compression hemostasis.

[0003] However, due to the complex shape of the abdominal cavity and related organs, the support structure of the hemostatic device is difficult to adjust according to the shape of the hemostatic location. As a result, when applying pressure to stop the bleeding, the compression device of the hemostatic device may apply excessive pressure to other locations in the abdominal cavity, which may lead to damage to other tissues in the patient's abdominal cavity. Summary of the Invention

[0004] This invention provides an adjustable intra-abdominal compression hemostasis device to solve the aforementioned technical problems.

[0005] The present invention adopts the following technical solution: it includes a pressing member; the pressing member is made of an elastic material, which can deform after being stretched and rebound after the stretching stops; the pressing member is provided with an expansion mechanism inside, which can adjust the size of the pressing area at the front end of the pressing member; and a hand handle is provided at the end of the pressing member.

[0006] Preferably, the handle is a cylindrical structure, and a support column is provided inside the handle. The outer wall of the support column is fixedly connected to the inner wall of the handle. Eight sliding grooves are provided at equal intervals around the outer side of the support column, and the two ends of each sliding groove extend to the front and rear ends of the support column, respectively.

[0007] Preferably, the expansion mechanism consists of eight sliders; the eight sliders are respectively arranged in eight corresponding grooves on the support column, and each slider can slide in the corresponding groove towards the front and rear ends of the support column;

[0009] Preferably, a baffle is provided at the front end of the support column; and a stop block is fixedly provided on the baffle at the part corresponding to each sliding groove.

[0010] Preferably, an adjusting post is provided inside the end of the handle, and the adjusting post is fixedly connected to four sliders arranged in a cross shape; an adjusting member is provided at the end of the handle, and the adjusting member is rotatably connected to the end of the handle. A sleeve that can be fitted onto the end of the adjusting post is fixedly provided at the bottom of the adjusting member. The sleeve has a threaded groove inside, and the end of the adjusting post has a thread that matches the threaded groove inside the sleeve. The threaded groove inside the sleeve and the thread on the adjusting post are in a threaded engagement state.

[0011] Preferably, an adjustment disc is provided inside the end of the handle, and the adjustment disc can move forward and backward inside the handle. The adjustment disc is fixedly connected to four other sliders arranged in a cross shape. A guide groove is provided on the handle, and a support rod is provided on the side of the adjustment disc. One end of the support rod is fixedly connected to the adjustment disc, and the other end of the support rod passes through the guide groove on the handle and extends outward for a certain distance. The adjustment disc is provided with a through groove for the adjustment column and the corresponding four sliders to move.

[0012] Preferably, a locking block is provided on the support rod at the outer region of the hand handle. The locking block is sleeved on the support rod and can extend and retract on the support rod in the direction of the hand handle to the inside and outside. Insertion holes are provided at both ends of the guide groove on the hand handle. An insertion rod that can be inserted into the insertion hole is fixedly provided on the side of the locking block facing the hand handle.

[0013] Preferably, the baffle is embedded in the support column by a limiting rod, the limiting rod can extend and move forward in the support column, and the front end of the limiting rod is fixedly connected to the baffle; a stop bar is provided laterally at the end of the limiting rod, and the support column and the handle are provided with limiting grooves for the movement of the stop bar; the end of the stop bar is fixedly connected to the limiting rod, and the front end of the stop bar passes through the limiting grooves of the support column and the handle, a threaded sleeve is fitted on the front end of the stop bar, and the outer side wall of the front end of the stop bar is provided with threads that are compatible with the threaded sleeve;

[0014] Preferably, a tension spring is provided between the connecting rod and the slider located at the end of the fixed rod. The two ends of the tension spring are fixedly connected to the slider and the corresponding connecting rod, respectively. Under the tension of the tension spring, the connecting rod can be pulled to tilt towards the front end of the slider.

[0015] By installing a tension spring between the connecting rod at the end of the fixed rod and the slider, the connecting rod in its natural state can be pulled by the tension spring and always produce an inclined movement towards the front end of the slider.

[0016] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0017] Firstly, the size of the compression area can be flexibly adjusted. Through two sets of cross-shaped staggered support members (eight in total) and corresponding slider components, the "full-size" and "half-size" compression areas of the front end of the compression member can be switched. When facing a large bleeding area, the eight support members can be adjusted to spread synchronously around the support column, expanding the elastic compression member to its maximum volume to ensure that the compression area completely covers the bleeding site. When dealing with a smaller bleeding point, four of the support members can be contracted and moved to the rear of another set of four support members, supporting the compression member with only four support members, reducing the compression area to half of its maximum size, and avoiding compression of surrounding normal tissues due to excessive compression.

[0018] The support component in this patent application adopts an arc-shaped design, which better conforms to the curved shape of the abdominal organs and tissues. At the same time, the expansion mechanism, through the rotational cooperation of the connecting rod and the slider, ensures that the support component always moves in parallel during the expansion process, ensuring that the contact between the compression component and the bleeding site is "surface contact" rather than "point contact", further improving the uniformity and adaptability of the compression, and solving the problem that the support structure of traditional devices is difficult to adjust to the complex shape of the abdominal cavity.

[0019] Secondly, this patent application allows for gradual adjustment of the support force by using the adjustment component and adjustment disc at the end of the handle. Operators can control the support force of the support component on the compression component through simple operations such as rotating the adjustment component and pushing the locking block, thereby controlling the pressure of the compression component on the bleeding site and avoiding tissue damage caused by excessive pressure. At the same time, the compression component is made of elastic material, and its own rebound characteristics can form "flexible compression" to reduce the hard impact on the tissues surrounding the bleeding site.

[0020] Meanwhile, through the "half-size" compression mode, the device can strictly limit the compression range to the area around the bleeding point, avoiding excessive compression of other organs in the abdominal cavity (such as the intestines, liver edges, etc.) caused by the non-adjustable compression area of ​​traditional devices, thus reducing the probability of postoperative complications such as tissue adhesion and organ function damage.

[0021] Thirdly, this patent application can be completed through three key steps: "rotating the adjusting component - pushing the locking block - moving the stop lever". Operators can quickly master the operation method. When stopping bleeding, operators can quickly open the compression component to the maximum state by rotating the adjusting component, align it with the bleeding site and complete the initial compression. Subsequently, the compression can be adjusted to the "half-size" mode according to the bleeding range, taking into account both hemostasis efficiency and safety.

[0022] Fourth, after the compression device comes into contact with the bleeding site, it can directly reduce vascular bleeding through the dual effects of sealing and packing compression. It can also activate the patient's own coagulation system through local pressure stimulation, accelerate the aggregation of coagulation substances, and improve the speed of hemostasis. At the same time, the fit of the elastic compression device can ensure that the compression pressure is continuously stable, avoiding repeated hemostasis due to pressure fluctuations. The efficient local compression can quickly control bleeding, reduce the excessive consumption of coagulation factors caused by massive blood loss, and reduce the risk of serious complications such as disseminated intravascular coagulation. Meanwhile, timely hemostasis helps to maintain stable blood pressure, buy time for subsequent treatment (such as surgical repair of blood vessels), and improve the patient's overall prognosis.

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0045] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0046] This invention provides an adjustable intra-abdominal compression hemostasis device, including a compression member 1; the compression member 1 is made of an elastic material, which can deform after being stretched and rebound after the stretching stops; the compression member 1 is provided with an expansion mechanism 2 inside, which can adjust the size of the compression area at the front end of the compression member 1; the compression member 1 is provided with a hand handle 3 at the end;

[0047] When in use, the expansion mechanism 2 can be operated according to the size of the location requiring compression for hemostasis within the abdominal cavity. The expansion mechanism 2 adjusts the size of the compression area at the front end of the compression member 1 from inside the compression member 1. Once the size is achieved, the operator can manipulate the handle 3 to insert the compression member 1 into the patient's abdominal cavity and then press the compression area at the front end of the compression member 1 onto the bleeding site. This seals the bleeding site by filling the compression member 1 with material to increase local pressure, thereby reducing outward bleeding from the blood vessels. After contacting the bleeding site, the compression member 1 can promote the activation of the coagulation system, thereby enhancing the hemostatic effect and improving the patient's blood pressure and coagulation substance consumption.

[0048] In a further preferred embodiment, the handle 3 is a cylindrical structure, and a support column 31 is provided inside the handle 3. The outer wall of the support column 31 is fixedly connected to the inner wall of the handle 3. Eight sliding grooves 32 are provided at equal intervals around the outer side of the support column 31, and the two ends of each sliding groove 32 extend to the front and rear ends of the support column 31, respectively.

[0049] The expansion mechanism 2 consists of eight sliders 21. Each slider 21 is respectively positioned within a corresponding groove 32 on the support column 31, and each slider 21 can slide within its corresponding groove 32 towards both ends of the support column 31. A fixed rod 22 is provided near the outer side of each slider 21. A support member 23, capable of supporting and expanding the interior of the compression member 1, is fixedly provided on the outer side of the fixed rod 22. The outer side of the support member 23 has an arc-shaped design. Two connecting rods 24 are provided between each fixed rod 22 and its corresponding slider 21. The same end of the two connecting rods 24 is rotatably connected to the slider 21, and the other end of the two connecting rods 24 is rotatably connected to the corresponding fixed rod 22. A baffle 33 is provided at the front end of the support column 31. A stop block 34 is fixedly provided on the baffle 33 at a location corresponding to each groove 32.

[0050] When the pressing member 1 needs to be opened, the slider 21 can be pushed towards the front end of the support column 31, so that the connecting rod 24 near the front end of the slider 21 gradually approaches the abutment 34 on the baffle 33. After the connecting rod 24 and the abutment 34 make contact, the abutment 34 will apply a blocking effect from the front side of the connecting rod 24. In the initial state, since the pressing member 1 has a certain rebound force, the pressing member 1 will apply pressure to the multiple internal support members 23 towards the central area of ​​the support column 31. Since there are two connecting rods 24 between the fixed rod 22 and the corresponding slider 21, the support member 23 and the fixed rod 22 will move towards the slider 21 in parallel under the traction of the two connecting rods 24 after being compressed, thereby forming a contracted state.

[0051] As the slider 21 drives the connecting rod 24 to continue pushing towards the front end of the support column 31, the connecting rod 24 will be pushed upward by the block 34. This will cause the connecting rod 24 near the front end of the slider 21 to gradually tilt towards the end of the slider 21. Since there are two connecting rods 24 between the fixed rod 22 and the corresponding slider 21, and the two ends of the two connecting rods 24 are rotatably connected to the corresponding fixed rod 22 and slider 21 respectively, the two connecting rods 24 will balance the pressure at both ends between the fixed rod 22 and the slider 21, so that the fixed rod 22 can only move towards the slider 21 in parallel and cannot tilt on the slider 21. As the connecting rod 24 near the front end of the slider 21 tilts towards the end of the slider 21, under the traction of the fixed rod 22 and the slider 21, the other connecting rod 24 will also tilt synchronously. The two connecting rods 24 will generate a pushing force between the fixed rod 22 and the slider 21, causing the fixed rod 22 to drive the support member 23 to gradually move away from the slider 21 in a parallel state.

[0052] When the eight support members 23 simultaneously expand from the contracted state to the surrounding area of ​​the support column 31, the eight support members 23 will simultaneously expand from the inside of the compression member 1 to the surrounding area, thereby expanding the compression member 1 with elastic properties and increasing the compression area at the front end of the compression member 1.

[0053] In a further preferred embodiment, an adjusting post 4 is provided inside the end of the hand handle 3, and the adjusting post 4 is fixedly connected to four sliders 21 arranged in a cross shape; an adjusting member 41 is provided at the end of the hand handle 3, and the adjusting member 41 is rotatably connected to the end of the hand handle 3. A sleeve 42 that can be sleeved on the end of the adjusting post 4 is fixedly provided at the bottom of the adjusting member 41. The sleeve 42 is provided with a threaded groove inside, and the end of the adjusting post 4 is provided with a thread that matches the threaded groove inside the sleeve 42. The threaded groove inside the sleeve 42 and the thread on the adjusting post 4 are in a threaded engagement state.

[0054] In a further preferred embodiment, an adjustment disc 43 is provided inside the end of the handle 3. The adjustment disc 43 can move forward and backward inside the handle 3. The adjustment disc 43 is fixedly connected to four other sliders 21 arranged in a cross shape. A guide groove 35 is provided on the handle 3. A support rod 44 is provided on the side end of the adjustment disc 43. One end of the support rod 44 is fixedly connected to the adjustment disc 43, and the other end of the support rod 44 passes through the guide groove 35 on the handle 3 and extends outward for a certain distance. A through groove 431 is provided on the adjustment disc 43 for the adjustment column 4 and the corresponding four sliders 21 to move.

[0055] A locking block 45 is provided on the support rod 44 at the outer region of the handle 3. The locking block 45 is sleeved on the support rod 44 and can extend and retract on the support rod 44 in the direction of the inner and outer sides of the handle 3. Insertion holes 36 are provided at both ends of the guide groove 35 on the handle 3. An insertion rod 46 that can be inserted into the insertion hole 36 is fixedly provided on the side of the locking block 45 facing the handle 3.

[0056] The baffle 33 is embedded in the support column 31 by a limiting rod 331. The limiting rod 331 can extend and move forward within the support column 31. The front end of the limiting rod 331 is fixedly connected to the baffle 33. A stop rod 332 is provided laterally at the end of the limiting rod 331. The support column 31 and the handle 3 are both provided with limiting grooves for the stop rod 332 to move. The end of the stop rod 332 is fixedly connected to the limiting rod 331, and the front end of the stop rod 332 passes through the limiting grooves of the support column 31 and the handle 3. A threaded sleeve 333 is fitted on the front end of the stop rod 332, and the outer side wall of the front end of the stop rod 332 is provided with threads that are compatible with the threaded sleeve 333.

[0057] A tension spring 25 is provided between the connecting rod 24 at the end of the fixed rod 22 and the slider 21. The two ends of the tension spring 25 are fixedly connected to the slider 21 and the corresponding connecting rod 24, respectively. Under the tension of the tension spring 25, the connecting rod 24 can be pulled to tilt towards the front end of the slider 21. By providing the tension spring 25 between the connecting rod 24 at the end of the fixed rod 22 and the slider 21, the connecting rod 24 in its natural state can always tilt towards the front end of the slider 21 due to the pulling action of the tension spring 25.

[0058] In this patent application, the support members 23 and the corresponding sliders 21 arranged in a cross pattern are divided into two groups. When one group of support members 23 contracts, the other group of support members 23 can contract and move to the rear area of ​​the first group of support members 23. This allows the compression member 1 to be supported and expanded only by the four support members 23 arranged in a cross pattern. Combined with the rebound characteristics of the compression member 1, the compression member 1, which was originally stretched by the four support members 23, is reduced to half its volume. The compression area at the front end of the compression member 1 is also reduced by half. This allows the compression member 1 to cope with smaller bleeding locations. When the operator uses this patent application, the reduced volume of the compression member 1 can compress and stop bleeding in smaller areas without compressing the surrounding tissues and avoiding compression damage to other normal tissues in the patient's abdominal cavity.

[0059] During operation, taking the compression member 1 to its maximum state as an example, when the adjusting member 41 is rotated, the sleeve 42 inside the adjusting member 41 will rotate synchronously. After the threaded groove inside the sleeve 42 forms a threaded engagement with the thread at the end of the adjusting column 4, the threaded groove inside the sleeve 42 will move in a spiral shape along the threaded trajectory on the adjusting column 4 towards the end of the hand handle 3. Since the slider 21 and the sliding groove 32 of the support column 31 are in a sliding engagement state, and are fixed by the adjusting column 4, the rotating sleeve 42 will cause the adjusting column 4 to generate a reaction force and drive the corresponding four cross-shaped sliders 21 to push towards the front end of the support column 31, thereby expanding the corresponding four support members 23 around the support column 31.

[0060] When the four support members 23 connected to the adjusting column 4 are opened, the gap between the four support members 23 can be used to place another four support members 23. At this time, the locking block 45 can be pushed towards the front end of the support column 31, so that the locking block 45 drives the support rod 44 and the adjusting plate 43 to move towards the front end of the support column 31 in sync. During the movement, the four sliders 21 connected to the adjusting column 4 will drive the corresponding four support members 23 to spread around the support column 31 and fill the gap between the four support members 23 that were originally opened. At this time, all eight support members 23 are in the opened state, so that the pressing member 1 can be opened to the maximum use state.

[0061] When it is necessary to expand the pressing member 1 to half-open state, the locking block 45 can be moved towards the end of the support column 31 to drive the corresponding adjusting plate 43 and the corresponding four sliders 21 to move. As the four sliders 21 in this part drive the corresponding support member 23 to move towards the end of the support column 31 in sync, the tension of the tension spring 25 can cause the corresponding connecting rod 24 to tilt towards the front end of the slider 21, thereby driving the corresponding four support members 23 to retract towards the support column 31 in a parallel state. During the operation, the locking block 45 can be moved quickly and continuously towards the end of the support column 31, so that the four support members 23 corresponding to the adjusting plate 43 are in a retracted state and move to the rear area of ​​the other four support members 23.

[0062] Subsequently, the stop bar 332 and threaded sleeve 333 can be moved towards the front end of the support column 31, causing the limit bar 331 to move the front end baffle 33 away from the front end of the support column 31, and the abutment 34 on the baffle 33 stops blocking the slide groove 32 and the corresponding connecting rod 24. At this time, under the action of the tension spring 25, the connecting rod 24 at the front end of the four support members 23 corresponding to the adjusting column 4 can be driven to tilt towards the front end of the slider 21, thereby causing the four support members 23 corresponding to the adjusting column 4 to contract and converge towards the front end of the support column 31, so that the four support members 23 in this part recombine into a support body with a smaller support area, thereby applying a smaller volume of support force to the inside of the compression member 1, so that the compression member 1, which was originally in an expanded state due to the eight internal support members 23, switches to a smaller volume, and reduces the compression area at the front end of the compression member 1 to half of the maximum state, thereby applying pressure to stop bleeding at smaller bleeding locations.
