Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and in particular relates to a subdural hematoma aspirator for neuroendoscopic procedures. Background Technology

[0002] The neuroendoscopic subdural hematoma aspirator is a tool used in minimally invasive surgery to remove chronic subdural hematomas (CSDH). This technique has advantages such as minimal trauma, rapid recovery, and high safety, and has become increasingly popular in clinical applications in recent years. Specifically, during neuroendoscopic surgery, the dura mater and the parietal capsule of the hematoma are usually incised first, and then the unliquefied hematoma is aspirated using a suction device under endoscopic visualization. In this confined space, the suction nozzle needs to be positioned flexibly to completely aspirate the hematoma.

[0003] Comparing with Chinese Patent No. CN211244823U, a visible intracranial hematoma aspirator is disclosed, including a base. An L-shaped damping shaft for adjusting the angle is rotatably connected to the upper surface of the base. A suction device holder for adjusting the position is fixedly connected to the front end of the L-shaped damping shaft. A sliding mechanism is provided on the inner wall of the suction device holder. A fixing sleeve is fixedly connected to the upper end of the sliding mechanism. A limiting mechanism for locking is provided at the upper end of the fixing sleeve. A suction device is provided inside the limiting mechanism. A suction mechanism for rinsing is provided inside the suction device.

[0004] However, the aforementioned patent can only move vertically, and the movement of the suction nozzle is limited, making it difficult to ensure complete suction of the hematoma. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a subdural hematoma aspirator for neuroendoscopic purposes, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A neuroendoscopic subdural hematoma aspirator includes a flexible tube that can be bent at an adjustable angle to aspirate the hematoma, and the tube is equipped with a control device for adjusting the bending angle.

[0008] The tubular device includes a connecting section, an intermediate section, and a suction section arranged in a connected manner. The connecting section is provided with a connector at its outer end, and the suction section is provided with a suction nozzle at its outer end.

[0009] The control device includes several traction components, each of which is connected to a braking element extending to the outer end of the connecting section.

[0010] Furthermore: the pulling component is an airbag, and the braking element is at least one air supply pipe connected to the airbag, with a pipe connector provided at the outer end of the air supply pipe.

[0011] Furthermore: eight airbags are evenly arranged, with four airbags forming a group, and the two groups of airbags are evenly distributed and staggered. They are respectively located at the connection between the connecting section and the middle section, and at the connection between the middle section and the suction section, so as to control the bending of the middle section and the suction section while the connecting section remains stationary, thereby changing the suction nozzle to any position.

[0012] Furthermore, the gas supply pipe extends from the connecting section, reducing the impact on the connector.

[0013] Furthermore, the eight pipe fittings and connectors are integrated together and uniformly plugged into the outside for easy disassembly and replacement.

[0014] Furthermore, the middle section is made of deformable plastic material, which ensures that the middle section can be bent smoothly.

[0015] Furthermore: the airbag is disposed on the inner wall or outer wall of the tubular device or is disposed through the tube wall.

[0016] Furthermore: the pulling component is a pulling rope installed inside or on the pipe wall of the pipe fitting device, and the braking element is formed by extending the pulling rope to the outer end of the connecting section. Four to eight pulling ropes are installed inside the pipe wall. The front end of the pulling rope extends into the suction section, and the rear end protruding from the connecting section is the braking part, i.e., the braking element. All braking components are connected to the central control unit. In the design, at least the angle between the bends in the middle section and the connecting section / suction section is adjustable, so that the angle can be adjusted by controlling the pulling of the corresponding pulling ropes through the central control unit.

[0017] Compared with existing technologies, the beneficial effects are:

[0018] 1. The flexible bending design allows the suction nozzle to be moved to any position, ensuring thorough suction of hematomas;

[0019] 2. The ease of operation is ensured by controlling the bending angle through air supply.

[0020] 3. The bending mechanism controlled by the expansion and contraction of the airbag reduces space occupation while ensuring suction effectiveness;

[0021] 4. Furthermore, this application is not limited to the surgical environment described in the background art above, but can also be used in surgeries on other parts of the body. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figures 1-2 Neuroendoscopic subdural hematoma aspirator

[0031] It includes a tubular device that can be bent and adjusted at an adjustable angle to aspirate hematomas, and the tubular device is equipped with a control device for adjusting the bending angle;

[0032] The tubular device includes a connecting section 101, an intermediate section 102 and a suction section 103 arranged in connection. The outer end of the connecting section 101 is provided with a connector 104, and the outer end of the suction section 103 is provided with a suction nozzle 105. The connecting section 101 is provided with a conventional pressure relief hole 3 for decompression and stress relief during surgery.

[0033] The control device includes several traction components 20, each of which is connected to a braking element extending to the outer end of the connecting section 101. The traction component 20 includes eight airbags 201, and the braking element is an air supply pipe 202 connected to each airbag 201, with a pipe connector 203 provided at the outer end of the air supply pipe 202.

[0034] The airbag 201 is a thin sheet that is adhered to the inner wall of the intermediate section 102. Alternatively, the airbag 201 can be embedded in the interlayer of the inner wall of the intermediate section 102. Even if fully inflated, it will not block the intermediate section 102. Figure 1Furthermore, the diameter of the hole drilled in the skull is only slightly larger than the diameter of the tubular device, so the bending angle is very small. In practice, the required adjustment angle is also small. Therefore, the airbag 201 does not need to expand too much; it only needs to expand to achieve small-angle adjustments in each section. Because the expansion range of the airbag 201 is limited, it will not block the intermediate section 102. Alternatively, the expansion of the airbag 201 can push the tubular device in the opposite direction, thereby achieving the effect of adjusting the angle of the suction section 103. For example, when the airbag 201 is located outside the tubular device, angle adjustments can be achieved at the bends of the connecting section 101, the intermediate section 102, and the suction section 103 by expansion and pushing, which may also have a pulling effect.

[0035] Furthermore: four airbags 201 form a group, and two groups of airbags 201 are evenly distributed and staggered, respectively set at the connection between the connecting section 101 and the intermediate section 102, and at the connection between the intermediate section 102 and the suction section 103, so as to control the bending of the intermediate section 102 and the suction section 103 while the connecting section 101 is stationary, thereby changing the suction nozzle 105 to any position; the air supply tube 202 extends out from the connecting section 101 to reduce the impact on the connector 104; the eight pipe joints 203 and the connector 104 are integrated together and uniformly plugged into the outside for easy quick disassembly and replacement; the intermediate section 102 is made of deformable plastic material with a certain strength to ensure smooth bending and effective support of the intermediate section 102.

[0036] The airbag 201 is installed on the inner wall or outer wall of the pipe fitting device or through the pipe wall. The airbag 201 can be installed in such a way as long as the angle of the suction section 103 can be easily adjusted under the operating environment and during use.

[0037] Example 2:

[0038] The difference from the above embodiments lies in that the pulling component 20 is a pulling rope located inside or on the surface of the pipe wall of the pipe fitting device. For example, a pulling rope channel 02 is provided on the pipe wall, and the entire pulling rope is located inside the pulling rope channel 02. The end of the connecting suction section 103 extends out of the pulling rope channel 02 and connects to the suction section 103, similar to the pulling principle of a brake cable. The braking element is formed by the pulling rope extending to the outer end of the connecting section 101. One or more pulling ropes are provided inside the pipe wall. The front end of the pulling rope extends into the suction section 103, and the rear end extending out of the connecting section 101 becomes the braking part, i.e., the braking element. All braking elements are connected to the main control 01. In the design, at least the angle between the two bends of the middle section 102 and the two bends of the connecting section 101 and the suction section 103 is adjustable, so that the angle can be adjusted by controlling the pulling of the corresponding pulling rope through the main control 01. The pull rope of the braking unit can be directly threaded through the connector 104 and connected to the main control 01, or the main control 01 can be directly installed on the connector 104 and the pull rope can be directly connected to the main control 01, or other methods that can achieve this design are acceptable.

[0039] Working principle: First, connect the tube connector 203 and the connector 104 to the external air source. Then, control the middle section 102 and the suction section 103 through the connecting section 101 to insert them into the subdural hematoma location. The hematoma is then sucked into the suction section 103 through the suction nozzle 105, and then suctioned out sequentially through the middle section 102 and the connecting section 101. When it is necessary to change the position of the suction nozzle 105, inflate or deflate the corresponding air bag 201 through the corresponding air supply tube 202 as needed. This causes the corresponding air bag 201 to expand or contract, creating a traction effect. Supported by the connecting section 101, this causes the middle section 102 to bend, and supported by the middle section 102, this causes the suction section 103 to bend, thereby changing the position of the suction nozzle 105. The air source can be controlled by a central control unit 01. For different angle requirements, the central control unit 01 can be used to quickly adjust the inflation and deflation of different air bags 201.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
