Description

Technical Field

[0001] The utility model relates to the technical field of endoscope auxiliary tools, in particular to an endoscope holding device. Background Art

[0002] Surgeries in neurosurgery and other departments typically require the participation of multiple surgeons, often using handheld endoscopes to assist in the procedure. Endoscopes used in neurosurgery are relatively small, typically only about 4mm in outer diameter. Surgeons typically wear gloves during surgery, which can become stained with liquids such as disinfectant, saline, and tissue fluid. The endoscope has a lubricating coating on its surface, and if liquids get on the surgeon's gloves, the endoscope will become slippery and difficult to hold. The endoscope has a lubricating coating on its surface, and if liquids get on the surgeon's gloves, the endoscope will become slippery and difficult to hold. Holding an endoscope for extended periods of time not only makes it difficult for the surgeon to control and manipulate it, but also leads to fatigue, causing the endoscope to vibrate and disrupt the normal surgical procedure. Summary of the Invention

[0003] In response to the deficiencies of the above-mentioned prior art, the present invention provides an endoscope holding device, in which a clamping piece is provided on the tube body, and a through hole for the passage of the endoscope tube is provided on the clamping piece, and the coaxial and non-coaxial changes between the through hole and the internal tube of the tube body are utilized to achieve the clamping and unclamping of the endoscope tube. When using an endoscope, the surgeon only needs to hold the device with one hand, and will not directly touch the tube of the endoscope, and will not contaminate or damage the endoscope tube. The outer diameter of the device can be set to be relatively thick, which is convenient for the surgeon's hand to hold without fatigue. The surgeon can control the clamping and loosening of the endoscope by pressing the clamping piece with his hand, and the clamping process is more stable and has less impact on the endoscope. It is specifically achieved through the following technologies.

[0004] An endoscope holding device comprises a tube body and a clamping member, wherein a first hole and a second hole are provided in the middle of the tube wall of the tube body; the first hole is a through hole, and the second hole is a through hole or a blind hole provided on the inner side of the tube wall of the tube body; the first hole and the second hole are symmetrically arranged with respect to the central axis of the tube body; the clamping member is inserted into the first hole and the second hole; a third hole is provided in the middle of the clamping member, and the third hole is a through hole, and the third hole is connected to the channel inside the tube body; an elastic member is provided between the clamping member and the tube wall of the tube body, and the elastic member controls the third hole to be coaxial or non-coaxial with the channel inside the tube body.

[0005] In the above-mentioned endoscope holding device provided by the present invention, the function of the first hole and the second hole is to insert the clamping member from the side wall of the tube body into the interior of the tube body, and the mutually aligned positional relationship of the first hole and the second hole can ensure that the clamping member will not be offset in the axial direction of the tube body. The interior of the tube body of this device is used for the endoscope pipeline to pass through, so the third hole is used to allow the endoscope pipeline to pass through from the inside. The clamping member can move back and forth along the direction of the first hole and the second hole. When it moves to a certain position, the third hole and the channel inside the tube body are coaxial, thereby allowing the endoscope to smoothly penetrate into the internal channel from one end of the tube body, pass through the third hole, and then extend from the other end of the tube body. When the clamping member moves back and forth along the direction of the first hole and the second hole, the elastic member can help the clamping member to achieve reset. When the clamping member is in the initial state, the third hole and the channel inside the tube body are not coaxial. At this time, the endoscope tube cannot pass through the channel inside the tube body into the third hole, and the elastic member is also in a natural unstretched or uncompressed state; after the clamping member is pressed to move, the third hole and the channel inside the tube body become coaxial. At this time, the endoscope tube can smoothly pass through the channel inside the tube body into the third hole, and the elastic member is stretched or compressed to produce elastic deformation.

[0006] It should be noted that the present device achieves the release and clamping of the endoscope by changing the coaxial or non-coaxial state of the third hole and the channel inside the tube body. Therefore, the diameter of the third hole and the channel inside the tube body do not necessarily have to be exactly the same as the diameter of the endoscope channel; however, they should be able to ensure that the endoscope channel can pass smoothly when coaxial, and at the same time, they should be able to prevent the endoscope from passing through the third hole when non-coaxial, or to provide a relatively tight clamping of the endoscope.

[0007] Optionally, the elastic member needs to be made of an elastic material, as long as it can automatically reset itself after the clamping member is pressed and released.

[0008] It should be noted that the position of the elastic member is not fixed and only needs to be specifically set based on the function to be achieved by the elastic member in the device.

[0009] Optionally, the elastic member may be provided at a location where the clamping member contacts the first hole.

[0010] Optionally, the elastic member may also be provided at a location where the clamping member contacts the second hole.

[0011] Optionally, since the wall of the tube body is relatively thick, the elastic member may also be buried inside the first hole or the second hole, or be provided in a channel inside the tube body.

[0012] Optionally, in order to prevent the clamping member from falling, the elastic member may also serve as a connecting member or a blocking member between the clamping member and the tube body.

[0013] It should also be noted that the shapes of the first hole, the second hole, and the third hole do not have to be circular. As long as the above functions can be achieved, the cross-sections of the above holes can be set to square or other shapes.

[0014] Generally, in order to facilitate production and processing, the first hole, the second hole, and the third hole are configured as circular holes.

[0015] Preferably, a limiting groove is provided on the outer side of the tube wall of the tube body; the limiting groove is located on any one side of the first hole or the second hole, or is symmetrically arranged on both sides of the first hole or the second hole; a limiting member is provided on the clamping member, and the limiting member corresponds to the limiting groove.

[0016] In the above preferred structure, in order to further prevent the clamping member from rotating in the first hole and the second hole, resulting in the third hole and the channel inside the tube body being unable to overlap, a limit groove and a limit member are provided to limit the clamping member so that it can only move in the direction of the line connecting the first hole and the second hole without rotating.

[0017] It should be noted that, based on the roles and functions of the limiting groove and the limiting member, the limiting groove does not necessarily need to be connected to the first hole or the second hole. The limiting groove does not necessarily need to be a through groove; the number of the limiting groove and the limiting member can also be one or more.

[0018] More preferably, in order to facilitate the production and processing of the tube body and the clamping member, one end of the limiting groove close to the first hole or the second hole is connected to the first hole or the second hole.

[0019] Preferably, to further stabilize the connection between the clamp and the tube, the device further includes an annular stopper, which is positioned outside the stopper groove. As the clamp moves in the direction of the line connecting the first and second holes, the stopper also moves within the stopper groove, along the depth of the groove. The stopper's blocking action prevents the clamp from falling out of the first hole.

[0020] More preferably, to facilitate assembly and disassembly of the tube body and the clamping member, as well as replacement of various components, the limiting pad is detachably disposed relative to the tube body. When the tube body and the clamping member need to be disassembled, the elastic member can be movably brought into contact with the tube body and the clamping member. By removing the limiting pad, the limiting member can be removed from the limiting groove, and the entire clamping member and the elastic member can then be removed.

[0021] To facilitate the removable attachment of the stop pad to the tube body, a further preferred structure comprises a first protrusion on the inner side of the stop pad, and a second protrusion or recess on the outer side of the tube body that matches the first protrusion. The first protrusion is located at a specific location on the inner side of the stop pad, and the second protrusion or recess is located at a specific location on the outer side of the tube body. The two cooperate to securely fit the stop pad onto the outer side of the stop slot.

[0022] In order to facilitate the detachable fixation between the limiting pad and the tube body, as a further preferred structure, the inner wall of the limiting pad is provided with an internal thread, and the tube wall of the tube body corresponding to the limiting groove is provided with an external thread matching the internal thread.

[0023] It should be noted that although the external thread is disconnected just outside the limiting groove, this does not affect the tightening of the limiting pad.

[0024] Preferably, the second hole is a blind hole arranged on the inner side of the tube wall of the tube body, and a fourth hole is provided at the bottom of the second hole, and the fourth hole is a through hole and has a smaller diameter than the second hole; a limiting column is provided at one end of the clamping member close to the second hole, and the limiting column is located in the fourth hole, and the elastic member is sleeved on the limiting column.

[0025] As a preferred structure of the shape and position of a clamping member and an elastic member, the second hole and the fourth hole are combined to form a step-like shape, and a step-like shape is also formed between the main body of the clamping member and the limiting column. The limiting column at one end of the clamping member can be inserted into the fourth hole, and the two ends of the elastic member respectively interfere with the two steps.

[0026] Preferably, in order to facilitate the surgeon to press the clamping member by hand, a button is provided at one end of the clamping member close to the first hole.

[0027] Preferably, the elastic member is a spring or a structure composed of elastic material.

[0028] Compared with the existing technology, the benefits of the present invention are: the device has a simple structure, is easy to assemble, and is easy to produce and process; it solves the problem that the surgeon's hands are very tired and easily fatigued when holding an endoscope, especially an endoscope used in neurosurgery; and it enables the surgeon to stably control and clamp the endoscope tube.

[0042] The following is a clear and complete description of the technical solution of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0043] The endoscope holding device provided by the present invention comprises a tube body 1 and a clamping member 2, wherein a first hole 3 and a second hole 4 are provided in the middle of the tube wall of the tube body 1; the first hole 3 is a through hole, and the second hole 4 is a through hole (such as Figure 1 、 2 As shown) or a blind hole provided on the inner side of the tube wall of the tube body 1 (as shown) Figure 2as shown); the first hole 3 and the second hole 4 are symmetrically arranged with respect to the central axis of the tube body 1; the clamping member 2 is inserted into the first hole 3 and the second hole 4; a third hole 5 is provided in the middle of the clamping member 2, and the third hole 5 is a through hole, and the third hole 5 is connected to the channel inside the tube body 1; an elastic member 6 is provided between the clamping member 2 and the tube wall of the tube body 1, and the elastic member 6 controls the third hole 5 to be coaxial or non-coaxial with the channel inside the tube body 1.

[0044] The endoscope holding device provided by the utility model has an initial state in which the channel inside the tube body and the third hole of the clamping member are not coaxial and are staggered to a certain extent. At this time, after the endoscope is inserted from one end of the tube body, the endoscope cannot be extended into the third hole. The operation process of this device is as follows: when using this device, the surgeon holds the tube body with his hand and presses the clamping member with his thumb from the end corresponding to the first hole, and the clamping member moves and compresses the elastic member; Figure 2 As shown, the pipe inside the tube body and the third hole reach a coaxial state, thereby allowing the endoscope to be inserted into the third hole and re-enter the channel inside the tube body from the other end, and finally extend from the other end of the tube body; when it is necessary to clamp and fix the endoscope, the thumb releases the clamping piece, and the clamping piece is reset under the elastic force of the elastic piece. However, due to the obstruction of the endoscope pipe in the third hole, it is impossible to completely reset, thereby forming a clamping force to clamp the endoscope pipe.

[0045] It should be noted that the function of the first hole and the second hole is to insert the clamping member into the interior of the tube body from the side wall of the tube body, and the mutually aligned positional relationship of the first hole and the second hole can ensure that the clamping member will not be offset in the axial direction of the tube body.

[0046] It should be noted that, based on the above operation process and the principle of clamping the endoscope tube, it can be known that the endoscope tube passes through the inside of the tube body of this device, so the third aperture must at least allow the endoscope tube to pass through from the inside.

[0047] It should be noted that the clamping member, under the action of the elastic member, can move back and forth along the first and second holes, and the elastic member can help the clamping member return to its original position. When moved to a certain position, the third hole is coaxial with the internal passage of the tube body, allowing the endoscope to smoothly pass through the internal passage of the tube body and the third hole. If the diameter of the third hole is exactly the same as the internal passage of the tube body, the third hole and the internal passage of the tube body will almost seamlessly connect.

[0048] It should be noted that, based on the operating principle of the present device, the aperture of the third hole and the channel diameter inside the tube body do not have to be exactly the same as the tube diameter of the endoscope; but they must be able to ensure that the endoscope tube can pass smoothly when coaxial, and at the same time, they must be able to prevent the endoscope from penetrating into the third hole when not coaxial, or to clamp the endoscope relatively tightly.

[0049] Generally, in order to make it easier for the surgeon to hold the device, the wall of the tube body of the device can be appropriately thicker according to the size of a normal human palm.

[0050] Except for the elastic parts which are made of elastic materials such as rubber and stainless steel, the other parts can be made of polymer materials with a certain hardness (such as nylon, PP, PC, etc.), which can reduce the overall weight of the device; lighter metal materials such as aluminum alloy can also be used.

[0051] In some embodiments, as Figure 1 、 2 As shown, the elastic member 6 is a rubber ring, which is sleeved on the clamping member 2. The rubber ring abuts against the outer side of the tube wall of the tube body 1 near the first hole 3. The rubber ring has good elasticity and can meet the movement and reset requirements of the clamping member 2.

[0052] In other embodiments, Figure 3 As shown, the elastic member 6 is a spring, which is sleeved on the clamping member 2 ; one end of the spring is fixed to the clamping member 2 , and the other end abuts against the outer side of the tube wall of the tube body 1 near the first hole 3 .

[0053] In some embodiments, as Figure 1 、 2 As shown, the second hole 4 is a through hole.

[0054] In other embodiments, Figure 3 As shown, the second hole 4 is a blind hole.

[0055] In other embodiments, Figure 4 As shown, the second hole 4 is a through hole, and the other end of the spring abuts against the outer side of the tube wall of the tube body 1 near the second hole 4 .

[0056] Optionally, the button can be processed with knurling, anti-slip patterns and other processing to increase friction, improve operator usability, and make it more convenient for the operator to install or remove the endoscope with one hand, which is ergonomic.

[0057] In some embodiments, as Figure 5 As shown, the outer side of the tube wall of the tube body 1 is provided with a limiting groove 8 ( Figure 5 The limiting groove 8 is located on one side of the first hole 3. The clamping member 2 is provided with a limiting member 9 corresponding to the limiting groove 8. During the entire movement of the clamping member, the limiting member remains within the limiting groove, thereby preventing the clamping member from rotating and causing the third hole to shift and become misaligned with the internal passage of the tube body.

[0058] It should be noted that, in addition to Figure 5In addition to the limit groove and limit member structure shown, based on the role and function of the limit groove and the limit member, the limit groove does not need to be connected to the first hole; the limit groove does not need to be a through groove; the number of the limit groove and the limit member can also be one or more.

[0059] Furthermore, in some embodiments, Figure 6 As shown, in order to facilitate the production and processing of the tube body 1 and the clamping member 2, the end of the limiting groove 8 close to the first hole 3 is connected to the first hole 3; Figure 6 In the embodiment, the limiting grooves and the limiting members are symmetrically arranged and two are respectively provided.

[0060] In some embodiments, as Figure 7 As shown, in order to make the installation between the clamping member 2 and the tube body 1 more stable, the device further includes an annular limiting pad 10 , which is sleeved on the outer side of the limiting groove 8 .

[0061] In some embodiments, in order to facilitate the disassembly and assembly of the tube body 1 and the clamping member 2 , as well as the replacement of various components, the limiting pad 10 is detachably arranged relative to the tube body 1 .

[0062] like Figure 8 As shown, a first protrusion 11 is provided on the inner side of the limiting pad 10 , and a second protrusion 12 matching the first protrusion 11 is provided on the outer side of the tube wall of the tube body 1 .

[0063] Or as Figure 9 As shown, the inner wall of the limiting pad 10 is provided with an internal thread 13, and the wall of the tube body 1 corresponding to the limiting groove 8 is provided with an external thread 14 matching the internal thread 13. Although the external thread is disconnected at the position facing the limiting groove, it does not affect the tightening of the limiting pad.

[0064] In some embodiments, Figure 8 The difference is that, Figure 10 、 11 As shown, the second hole 4 is a blind hole provided on the inner side of the tube wall of the tube body 1, and a fourth hole 15 is provided at the bottom of the second hole 4. The fourth hole 15 is a through hole and has a smaller diameter than the second hole 4; a limiting post 16 is provided at one end of the clamping member 2 close to the second hole 4, and the limiting post 16 is located in the fourth hole 15. The elastic member 6 (spring) is sleeved on the limiting post 16. Figure 11 It can be seen that after releasing the button, the clamping member is reset upward, so the position of the endoscope pipeline is slightly above the channel inside the tube body, which shows that the endoscope pipeline has been firmly clamped.

[0065] In some embodiments, as Figure 1-11 As shown, a button 7 is provided at one end of the clamping member 2 close to the first hole 3 .

[0066] The above-mentioned endoscope holding device provided by the present invention is provided with a clamping piece on the tube body, and a through hole for the endoscope tube to pass through is provided on the clamping piece. The coaxial and non-coaxial changes between the through hole and the tube inside the tube body are utilized to achieve the clamping and unclamping of the endoscope tube. When using the endoscope, the surgeon only needs to hold the device with one hand, without directly contacting the tube of the endoscope, and without contaminating or damaging the endoscope tube. The outer diameter of the device can be set to be relatively thick, which is convenient for the surgeon's hand to hold without fatigue. The surgeon can control the clamping and loosening of the endoscope by pressing the clamping piece with his hand. The clamping process is more stable and has less impact on the endoscope.

[0067] The above specific embodiments describe the implementation of the present invention in detail, but the present invention is not limited to the specific details of the above embodiments. Within the scope of the claims and technical concept of the present invention, various simple modifications and changes can be made to the technical solution of the present invention, and these simple modifications are all within the scope of protection of the present invention.
