Description

Technical Field

[0001] The utility model relates to a hemostatic device, in particular to a quick hemostatic device which can quickly stop blood.

[0002] The utility model also relates to an interventional medical set with the rapid hemostasis device. Background Art

[0003] Currently, with the advancement of medical technology, more and more surgeries, sampling, and treatments are being performed using minimally invasive interventions. Minimally invasive treatments or sampling procedures involve inserting a cannula into which a sampling needle, biopsy needle, or ablation needle—a sampling or treatment device—is inserted. This cannula is then advanced to the area to be sampled or treated. Continued advancement causes the sampling device to begin sampling, or the treatment device to begin treatment, such as ablation. After sampling or treatment, and after the sampling or treatment device is removed, bleeding may occur. Currently, medical personnel manually rub a cotton swab into the sampling or treatment port. However, because the sampling and treatment ports are sometimes far from the skin surface, the cotton swab is rough and cannot penetrate the wound quickly enough. This can lead to bleeding that cannot be stopped in time, resulting in blood loss and even life-threatening situations. Furthermore, the hand-rubbed cotton swab can be contaminated with bacteria, and contact with the sampling or treatment wound can inevitably lead to wound infection, leading to more serious subsequent problems. Utility Model Content

[0004] The purpose of the utility model is to overcome the technical problems in the prior art and provide a rapid hemostasis device with a relatively simple structure that can quickly deliver a sterile hemostatic strip to the wound location for sampling and treatment to stop bleeding quickly and effectively.

[0005] The technical solution of the utility model is as follows: it comprises: a hemostatic sleeve, a pushing rod and a hemostatic strip, the front end of the hemostatic sleeve is releasably docked with the rear end of an interventional outer sleeve used in medical and surgical treatment, the hemostatic strip is pre-arranged inside the hemostatic sleeve, and a front-to-back through-hemostatic channel is arranged inside the hemostatic sleeve along its long axis direction, the hemostatic strip is extended along the long axis direction in the hemostatic channel, the front end of the hemostatic channel is docked with the rear end of a delivery channel arranged in the center of the interventional outer sleeve, the pushing rod is releasable and pushes the hemostatic strip from the rear end of the hemostatic channel into the hemostatic channel and the delivery channel in sequence until the hemostatic strip finally abuts against the bleeding area.

[0006] The rapid hemostasis device of the present invention can also be:

[0007] The size of the hemostatic channel inside the hemostatic sleeve gradually decreases from back to front, the radial size of the hemostatic strip is smaller than the internal size of the delivery channel, and the front end size of the hemostatic channel is greater than or equal to the rear end size of the delivery channel.

[0008] The hemostatic channel is in a cone shape or a cylindrical shape.

[0009] The hemostatic channel is in the shape of a truncated cone or a truncated pyramid.

[0010] The interventional outer sleeve includes an outer sleeve body, which is releasably docked with the hemostatic sleeve through a connecting sleeve block, and the rear end of the connecting sleeve block is releasably docked with the front end of the hemostatic sleeve. A connecting channel is provided in the connecting sleeve block, and the delivery channel includes a tube channel. The connecting channel is connected and docked with the hemostatic channel through the tube channel, and the pushing rod pushes the hemostatic strip through the tube channel and the connecting channel and abuts against the bleeding area.

[0011] The front end of the hemostatic sleeve and the rear end of the connecting sleeve block can be releasably connected by plugging, snapping, buckling, threading or interference fitting.

[0012] The hemostatic sleeve is provided with a forward-extending insert, and a forward-concave slot is provided at a corresponding position of the connecting sleeve, and the insert can be releasably inserted into the slot; or the rear end of the connecting sleeve is provided with a backward-extending insert, and a backward-concave slot is provided at a corresponding position of the front end of the hemostatic sleeve, and the insert can be releasably inserted into the slot.

[0013] The rear end of the connecting sleeve is provided with a slot, and the front end of the hemostatic sleeve is provided with a buckle, and the hemostatic sleeve is releasably engaged in the slot through the buckle and is releasably engaged with the connecting sleeve; or the rear end of the connecting sleeve is provided with a buckle, and the front end of the hemostatic sleeve is provided with a slot, and the hemostatic sleeve is releasably engaged in the slot through the buckle and is releasably engaged with the connecting sleeve.

[0014] The front and rear ends of the hemostatic sleeve are provided with blocking cards, and the blocking cards block the hemostatic strip in the hemostatic channel.

[0015] The utility model provides a rapid hemostasis device, comprising: a hemostasis sleeve, a pushing rod and a hemostasis strip. The front end of the hemostasis sleeve is releasably docked with the rear end of an interventional outer sleeve used in medical and surgical treatment processes. The hemostasis strip is pre-arranged inside the hemostasis sleeve. A front-to-back through-hemostasis channel is arranged inside the hemostasis sleeve along its long axis direction. The hemostasis strip is extended along the long axis direction in the hemostasis channel. The front end of the hemostasis channel is docked with the rear end of a delivery channel arranged in the center of the interventional outer sleeve. The pushing rod is releasable and pushes the hemostasis strip from the rear end of the hemostasis channel into the hemostasis channel and the delivery channel in sequence until the hemostasis strip finally abuts against the bleeding area.

[0016] In this way, after sampling and treatment, the interventional overtube is still in the patient's body. After the sampling device or treatment device is pulled out from the interventional overtube, the hemostatic cannula with the built-in hemostatic strip is quickly docked with the interventional overtube, and then the pushing rod is inserted into the hemostatic channel from the rear of the hemostatic cannula, and then the hemostatic strip is quickly pushed forward. After passing through the hemostatic channel, the hemostatic strip enters the delivery channel, and finally reaches the bleeding area of the wound after sampling or treatment to stop bleeding. The hemostatic strip squeezes the blood so that it absorbs, expands, and forms a thrombus, preventing blood from seeping out of the wound. Because the pushing rod has a relatively large force and is easy to apply, it is easier to push the hemostatic strip, and the front end of the interventional overtube is facing the bleeding area of the wound, so the hemostatic strip is accurately positioned. Because the sterile hemostatic strip is pre-placed in the hemostatic channel of the hemostatic sleeve, manual rubbing is no longer required during use, saving time. Simultaneously, due to the rapid pushing of the push rod, bleeding can be quickly stopped, requiring only 1 / 10 of the time of the original manual rubbing and insertion method, saving more than 90% of the time. Furthermore, because the hemostatic strip does not come into contact with the hands or the outside world throughout the entire process, the adverse effects of bacterial infection of the wound are avoided. Therefore, the advantages of the rapid hemostatic device of the utility model over the prior art are: a relatively simple structure, the ability to quickly deliver the sterile hemostatic strip to the wound site for sampling and treatment to stop bleeding, rapid and effective hemostasis, and safe and sterile.

[0017] Another object of the present invention is to overcome the technical problems in the prior art and to provide an interventional medical kit with a rapid hemostasis device that has a relatively simple structure and can quickly deliver sterile hemostasis strips to the wound site for sampling and treatment to stop bleeding quickly and effectively.

[0018] The technical solution of the interventional medical set of the present invention is as follows: it comprises: an interventional outer sleeve, an interventional treatment device and / or an interventional sampling device, and a rapid hemostasis device. The front and middle parts of the interventional treatment device and / or the interventional sampling device used for interventional treatment or interventional sampling can be releasably inserted into the front middle part of the interventional outer sleeve, and the front end of the interventional treatment device and / or the interventional sampling device extends out of the front end of the interventional outer sleeve and corresponds to the treatment area or the sampling area. The rapid hemostasis device can be releasably docked with the rear end of the interventional outer sleeve. The rapid hemostasis device comprises: a hemostasis sleeve, a push-pull sleeve, and a push-pull sleeve. Rod and hemostatic strip, the front end of the hemostatic sleeve is releasably docked with the rear end of an interventional outer sleeve used in medical and surgical treatment processes, the hemostatic strip is pre-arranged inside the hemostatic sleeve, and the interior of the hemostatic sleeve is provided with a front-to-back through-hemostatic channel along its long axis direction, the hemostatic strip is extended along the long axis direction in the hemostatic channel, the front end of the hemostatic channel is docked with the rear end of a delivery channel provided in the center of the interventional outer sleeve, the pushing rod is releasable and pushes the hemostatic strip from the rear end of the hemostatic channel into the hemostatic channel and the delivery channel in turn until the hemostatic strip finally abuts against the bleeding area.

[0019] In this way, the interventional medical kit contains various components that are sterile and sealed and are in a sterile state. When in use, the sterile package is torn open and the interventional overtube is inserted into the position of the body that requires sampling and treatment by medical means. Then the sampling device and the treatment device are inserted into the interventional overtube and further pushed forward to take samples or start treatment. After the treatment, the sampling device or the treatment device is pulled out, and the hemostatic cannula is directly connected to the rear end of the interventional overtube. Then, the pushing rod is used to quickly push the hemostatic strip built into the hemostatic channel of the hemostatic cannula toward the wound. The hemostatic strip moves to the wound area and continues to push the pushing rod so that the hemostatic strip stops bleeding in the bleeding area of the wound. After sampling and treatment, the interventional overtube is still in the patient's body. After the sampling device or treatment device is pulled out from the interventional overtube, the hemostatic cannula with the built-in hemostatic strip is quickly docked with the interventional overtube, and then the pushing rod is inserted into the hemostatic channel from the rear of the hemostatic cannula, and then the hemostatic strip is quickly pushed forward. After passing through the hemostatic channel, the hemostatic strip enters the delivery channel, and finally reaches the bleeding area of the wound after sampling or treatment to stop bleeding. The hemostatic strip squeezes the blood to cause it to swell and form a thrombus, thereby preventing the blood from seeping out of the wound. Because the pushing rod has a relatively large force and is easy to apply, it is easier to push the hemostatic strip, and the front end of the interventional overtube is facing the bleeding area of the wound, so the hemostatic strip is accurately positioned. Because the sterile hemostatic strip is pre-placed in the hemostatic channel of the hemostatic cannula, manual rubbing is no longer required during use, saving time. Furthermore, the rapid pushing of the push rod allows for rapid hemostasis, requiring only 1 / 10 the time of manual insertion, saving 90% of the time. Furthermore, because the hemostatic strip does not come into contact with the hand or the outside world during the entire process, the adverse effects of bacterial infection on the wound are avoided.

[0020] Therefore, the advantages of the interventional medical kit with the above-mentioned rapid hemostasis device of the present invention over the prior art are: relatively simple structure, ability to quickly deliver sterile hemostatic strips to the wound site for sampling and treatment to stop bleeding, rapid and effective hemostasis, safe and sterile.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and in combination with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] This utility model is a quick hemostasis device, please refer to Figures 1 to 6The relevant figures include: a hemostatic sleeve 1, a pushing rod 4 and a hemostatic strip 2. The front end of the hemostatic sleeve 1 is releasably docked with the rear end of an interventional outer sleeve 5 used in medical and surgical treatment. The hemostatic strip 2 is pre-arranged inside the hemostatic sleeve 1. A front-to-back through-hemostatic channel 3 is arranged inside the hemostatic sleeve 1 along its long axis. The hemostatic strip 2 is extended along the long axis in the hemostatic channel 3. The front end of the hemostatic channel 3 is docked with the rear end of the delivery channel arranged in the center of the interventional outer sleeve 5. The pushing rod 4 is releasable and pushes the hemostatic strip 2 from the rear end of the hemostatic channel 3 into the hemostatic channel 3 and the delivery channel in turn until the hemostatic strip 2 finally abuts against the bleeding area. In this way, after sampling and treatment, the interventional outer sleeve 5 is still in the patient's body. After the sampling device or treatment device is pulled out from the interventional outer sleeve 5, the hemostatic sleeve 1 with the built-in hemostatic strip 2 is quickly docked with the interventional outer sleeve 5, and then the push rod 4 is inserted into the hemostatic channel 3 from the rear of the hemostatic sleeve 1, and then the hemostatic strip 2 is quickly pushed forward. After passing through the hemostatic channel 3, the hemostatic strip 2 enters the delivery channel and finally reaches the bleeding area of the wound after sampling or treatment to stop bleeding. The hemostatic strip squeezes the blood so that it is absorbed, expanded, and forms a thrombus to prevent blood from seeping out of the wound. Because the push rod 4 has a relatively large force and is easy to apply, it is easier to press, and the front end of the interventional outer sleeve 5 is facing the bleeding area of the wound, so the hemostatic strip 2 is accurately positioned. Because the sterile hemostatic strip 2 is pre-placed in the hemostatic channel 3 of the hemostatic sleeve 1, there is no need to manually rub it during use, which saves time. At the same time, due to the rapid pushing of the push rod 4, bleeding can be stopped quickly, and only 1 / 10 of the time required for the original manual rubbing and insertion is required, saving 90% of the time. In addition, since the hemostatic strip 2 does not touch the hands or the outside world throughout the entire process, it avoids the adverse effects of bacterial infection on the wound. Therefore, the advantages of the quick hemostatic device of the utility model over the prior art are: the structure is relatively simple, the sterile hemostatic strip 2 can be quickly transported to the wound location for sampling and treatment to stop bleeding, and the hemostasis is fast, effective, safe and sterile. Furthermore, the hemostatic strip can be a hemostatic gelatin sponge strip or a hemostatic strip made of hemostatic silk. The length and width of the hemostatic strip are determined in different specifications according to actual use needs.

[0033] This utility model is a quick hemostasis device, please refer to Figures 1 to 6In the relevant figures, based on the previous technical solution, it can also be that: the size of the hemostatic channel 3 inside the hemostatic sleeve 1 gradually decreases from back to front, the radial size of the hemostatic strip 2 is smaller than the internal size of the delivery channel, and the front end size of the hemostatic channel 3 is greater than or equal to the size of the rear end of the delivery channel. In this way, the hemostatic strip 2 is more easily pushed by the push rod 4 and quickly moves in the hemostatic channel 3 and the connecting channel 9 toward the bleeding area for sampling or treating the wound and is more easily pushed to the bleeding area, achieving rapid hemostasis. A rapid hemostasis device of the present invention, based on the previous technical solution, further preferably has the following technical solution: the hemostatic channel 3 is in the shape of a cone or a cylinder. In this way, it is easier for the push rod 4 to push the hemostatic strip 2. Of course, it can also be further configured that: the shape of the hemostatic channel 3 is a truncated cone or a prism cone. Both of these can achieve faster advancement of the hemostatic strip 2 in the hemostatic channel 3. Of course, the most preferred technical solution is that the hemostatic channel 3 is in the shape of a frustum, because the friction between the frustum hemostatic channel 3 and the hemostatic strip 2 is lower, avoiding the additional force due to the contact of sharp corners, so that the hemostatic strip 2 can be pushed into the bleeding area as quickly as possible to stop bleeding. A rapid hemostatic device of the utility model, based on the technology of the previous technical solution, can also be provided with blocking cards at the front and rear ends of the hemostatic sleeve, and the blocking cards block the hemostatic strip in the hemostatic channel. In this way, when the size of the hemostatic strip is smaller than the size of the hemostatic channel, the blocking cards provided at the front and rear ends of the hemostatic sleeve can block the hemostatic strip in the hemostatic channel of the hemostatic sleeve to prevent it from falling out.

[0034] The present invention provides a rapid hemostasis device, which is a further preferred embodiment of the above technical solutions. The interventional overtube 5 includes an overtube body 7, which is releasably docked with the hemostatic cannula 1 via a connecting sleeve 8. The rear end of the connecting sleeve 8 is releasably docked with the front end of the hemostatic cannula 1. The connecting sleeve 8 is provided with a connecting channel 9. The delivery channel includes a tubular channel 10. The connecting channel 9 is connected and docked with the hemostatic channel 3 via the tubular channel 10. The pushing rod 4 pushes the hemostatic strip 2 through the tubular channel 10 and the connecting channel 9 to contact the bleeding area. In this way, the interventional overtube 5 and the hemostatic cannula 1 can be releasably docked via the connecting sleeve 8. During use, because interventional medical treatment is minimally invasive, the part involved in the patient's body is as small as possible. If the overtube body 7 is directly docked with the hemostatic cannula 1 during docking, the alignment accuracy is not high, and excessive force may cause the overtube body 7 to penetrate deeper, affecting the patient's feeling. In this way, the rear end of the outer cannula body 7 is fixed by a relatively large connecting sleeve block 8, ensuring that the depth and position of the outer cannula body 7 inserted into the patient's body will no longer move left or right. At the same time, because the connecting sleeve block 8 is relatively large, the hemostatic sleeve 1 is relatively easy to releasably dock with the connecting sleeve block 8, thereby making it relatively easy for the hemostatic channel 3 to dock with the connecting channel 9, making it convenient to dock as quickly as possible. At the same time, it is convenient for the hemostatic strip 2 to smoothly reach the bleeding area under the action of the push rod 4 and ultimately stop bleeding quickly. Of course, the connecting channel 9 in the connecting sleeve block 8 can also be shaped like a cone with a size gradually decreasing from back to front. This makes it easier for the hemostatic strip 2 to quickly enter the tube channel 10, avoiding hitting the tube wall and blocking the outer cannula body 7 and the tube channel 10.

[0035] The utility model provides an interventional medical set, wherein the front end of the hemostatic sleeve 1 and the rear end of the connecting sleeve 8 are releasably plug-in, snap-on, buckled, threaded, or interference-fit connected. Such a connection method can facilitate the rapid docking of the hemostatic sleeve 1 and the connecting sleeve 8 without misalignment, and will not separate again to affect the overall hemostasis speed. The specific method can be: the hemostatic sleeve 1 is provided with a forward-extending insert 11, and the corresponding position of the connecting sleeve 8 is provided with a forward-concave slot 12, and the insert 11 is releasably plugged into the slot 12; or the rear end of the connecting sleeve 8 is provided with a backward-extending insert 11, and the corresponding position of the front end of the hemostatic sleeve 1 is provided with a backward-concave slot 12, and the insert 11 is releasably plugged into the slot 12. In this way, during use, the hemostatic sleeve 1 and the connecting block 8 are directly connected by plugging the insert into the corresponding slot 12. Then, the push rod 4 is inserted into the hemostatic channel 3 of the hemostatic sleeve 1, and the hemostatic strip 2 is pushed forward to the bleeding area to quickly stop bleeding. After the bleeding stops, the push rod 4 is dragged backward and removed. Then, the plug 11 and the slot 12 are disconnected, and the hemostatic sleeve 1 is removed and disconnected from the connecting block 8, completing the entire hemostatic process. Because the insert and the slot 12 are releasably connected, the hemostatic sleeve 1 and the connecting block 8 are fixed together and cannot be separated or rotated, thereby ensuring that the hemostatic strip 2 built into the hemostatic sleeve 1 can quickly stop bleeding. Of course, other docking methods can also be adopted, for example: the rear end of the connecting sleeve 8 is provided with a slot, the front end of the hemostatic sleeve 1 is provided with a buckle, and the hemostatic sleeve 1 is releasably engaged in the slot by the buckle and is releasably engaged with the connecting sleeve 8; or the rear end of the connecting sleeve 8 is provided with a buckle, the front end of the hemostatic sleeve 1 is provided with a slot, and the hemostatic sleeve 1 is releasably engaged in the slot by the buckle and is releasably engaged with the connecting sleeve 8. In this way, during use, the hemostatic sleeve 1 and the connecting sleeve 8 are quickly docked by the engagement of the buckle and the slot, which facilitates the docking of the hemostatic sleeve 1 and the connecting channel 9, further ensuring that the hemostatic strip 2 can pass through the hemostatic channel 3, the connecting channel 9 and the tube channel 10 and then directly act on the bleeding area to quickly stop bleeding.

[0036] The utility model provides an interventional medical kit, comprising: an interventional outer sleeve 5, an interventional treatment device and / or an interventional sampling device, and a rapid hemostasis device. The front and middle parts of the interventional treatment device 6 and / or the interventional sampling device used for interventional treatment or interventional sampling can be releasably inserted into the front middle part of the interventional outer sleeve 5, and the front end of the interventional treatment device 6 and / or the interventional sampling device extends out of the front end of the interventional outer sleeve 5 to correspond to the treatment area or the sampling area. The rapid hemostasis device can be releasably docked to the rear end of the interventional outer sleeve 5. The rapid hemostasis device is the rapid hemostasis device described above. In this way, in the interventional medical kit, all the components are sterile and sealed and are in a sterile state. When in use, after tearing open the sterile package, the interventional overtube 5 is inserted into the position of the body that requires sampling and treatment by medical means, and then the sampling device and the treatment device are inserted into the interventional overtube 5 and further pushed forward to take samples or start treatment. After the treatment, the sampling device or the treatment device is pulled out, and the hemostatic cannula 1 is directly docked to the rear end of the interventional overtube 5, and then the pushing rod 4 is quickly used to push the hemostatic strip 2 built into the hemostatic channel 3 of the hemostatic cannula 1 toward the wound, and the hemostatic strip 2 moves to the wound area to stop bleeding. Therefore, after sampling and treatment, the interventional outer sleeve 5 is still in the patient's body. After the sampling device or treatment device is pulled out from the interventional outer sleeve 5, the hemostatic sleeve 1 with the built-in hemostatic strip 2 is quickly docked with the interventional outer sleeve 5, and then the push rod 4 is inserted into the hemostatic channel 3 from the rear of the hemostatic sleeve 1, and then the hemostatic strip 2 is quickly pushed forward. After passing through the hemostatic channel 3, the hemostatic strip 2 enters the delivery channel, and finally reaches the bleeding area of the wound after sampling or treatment to stop bleeding and prevent blood from seeping out of the wound. Because the push rod 4 has a relatively large force and is easy to apply, it is easier to stop bleeding, and the front end of the interventional outer sleeve 5 is facing the bleeding area of the wound, so the hemostatic strip 2 is accurately positioned, and the external push of the push rod 4 can quickly stop bleeding. Because the sterile hemostatic strip 2 is built into the hemostatic channel 3 of the hemostatic sleeve 1, manual rubbing is no longer required during use, saving time. At the same time, due to the rapid pushing of the push rod 4, bleeding can be quickly stopped, requiring only 1 / 10 of the time of the original manual rubbing and insertion method, saving 90% of the time. In addition, since the hemostatic strip 2 does not touch the hands or the outside world throughout the entire process, it avoids the adverse effects of bacterial infection of the wound. Therefore, the interventional medical set with the above-mentioned rapid hemostasis device of the utility model has the following advantages over the prior art: it has a relatively simple structure, can quickly transport the sterile hemostatic strip 2 to the wound location for sampling and treatment to stop bleeding, and stops bleeding quickly and effectively, safely and sterilely.The interventional sampling device described above may be a biopsy needle, a sampling needle, or the like, and the interventional treatment device 6 may be an ablation needle, a puncture needle, a cutting needle, a cutting knife, or other interventional treatment devices.
