Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of endoscopes, and in particular relates to an endoscope-assisted diagnosis and treatment device. Background Art
[0002] In the medical field, endoscopes are widely used in clinical practice because of their obvious advantages in inspection and treatment, such as direct viewing of images, easy operation, integrated diagnosis and treatment, and minimally invasive treatment. Endoscopes can not only assist in diagnosis and treatment, but also use matching instruments to enter the human body through the endoscope's forceps channel to reach the lesion, achieving non-invasive or minimally invasive treatment while inspecting.
[0003] In the related technology, the typical structure of the instrument supporting the endoscope is that the slip ring and the clamp head are connected by a cable, and a spring tube is provided outside the cable to strengthen it. The opening and closing of the clamp head are controlled by pushing and pulling the slip ring. The slip ring is sleeved on the outside of the handle, and a spring tube is connected between the handle and the clamp head. When the operator rotates the handle, the spring tube drives the clamp head to rotate.
[0004] Since the portion of the structure entering the pliers channel is slender, the torque of the spring tube itself will affect the transmission of the rotation of the handle to the pliers head. The structure has poor torque transmission performance, that is, the pliers head does not respond accurately or unresponsively to the rotation of the handle. Utility Model Content
[0005] In view of this, the utility model provides an endoscope-assisted diagnosis and treatment device to solve the problem in the related art that the forceps head of the endoscope supporting instrument is not sensitive to the rotation of the handle.
[0006] The utility model provides an endoscope-assisted diagnosis and treatment device, comprising a forceps head and a handle, the endoscope-assisted diagnosis and treatment device also comprising an outer tube, one end of the outer tube is connected to the forceps head, the other end of the outer tube is connected to the handle, the outer tube comprises an inner layer and an outer layer covering the outer side of the inner layer, the inner layer is a flexible tube, and the outer layer is suitable for tightly wrapping the inner layer and transmitting the torque applied to the handle to the forceps head.
[0007] The beneficial effect is that the outer layer is wrapped around the outer side of the inner layer, and the outer layer can tightly wrap the inner layer, limiting the torque of the inner layer itself. When the operator turns the handle, the torque applied to the handle can be accurately transmitted to the clamp head without being affected by the torque of the inner layer itself, thereby improving the torque transmission performance of the outer tube, allowing the clamp head to rotate with the rotation of the handle, and then when the operator operates the handle on the outside, the rotation angle of the clamp head can be guaranteed to accurately sample living tissue.
[0008] In some embodiments, the outer layer is wrapped around the outer surface of the inner layer.
[0009] The beneficial effect is that the outer layer is wound around the outer surface of the inner layer, which can better wrap the inner layer tightly, limit the torque of the inner layer itself, and thus improve the torque transmission ability of the outer tube.
[0010] In some embodiments, the outer layer is a tubular structure formed by winding a hard material around the inner layer.
[0011] The beneficial effect is that after the hard material is wound around the inner layer, a tubular structure can be formed, so that the outer layer can cover the inner layer from the outside, and the inner layer and the outer layer form an integral body. This not only makes the whole outer tube have a certain flexibility due to the existence of the inner layer, which is convenient for entering the human body, but also the outer layer ensures the torque transmission ability from the handle to the clamp head.
[0012] In some embodiments, the hard material constituting the outer layer is a metal wire.
[0013] In some embodiments, the outer layer has a mesh structure.
[0014] The beneficial effect is that the metal wire is wound around the outer wall of the inner layer in a mesh structure, so that the outer layer forms a metal braided mesh layer. In this way, after transmitting different torques, it is not easy to deform, thereby extending the service life of the outer tube, and the outer layer can also avoid some losses caused by collision and cutting, ensuring the overall service life of the endoscopic auxiliary diagnosis and treatment device.
[0015] In some embodiments, the inner layer is a spring tube.
[0016] The beneficial effect is that the inner layer is set as a spring tube, which can better adapt to human organs, such as the curved intestine. It can facilitate the entry of the endoscopic auxiliary diagnosis and treatment device into the human body, and at the same time can play a certain strengthening role for the internal cable.
[0017] In some embodiments, the endoscopic auxiliary diagnosis and treatment device further includes a protective tube, and the protective tube is sleeved outside the outer tube.
[0018] The beneficial effect is that the protective tube can play a certain protective role for the outer tube, further extending the service life of the outer tube, and at the same time can protect the endoscopic auxiliary diagnosis and treatment device from being easily worn by the outside.
[0019] In some embodiments, the inner layer encloses an avoidance space that can penetrate along the length direction, and the endoscopic auxiliary diagnosis and treatment device further includes: a sliding member connected to the handle along the length direction of the handle; a cable, passing through the avoidance space, and one end of the cable is connected to the clamp head, and the other end of the cable is connected to the sliding member.
[0020] The beneficial effect is that by connecting the sliding member and the clamp head with a cable, the operator can slide the sliding member outside to control the opening and closing of the clamp head, and the operation is relatively convenient.
[0021] In some embodiments, the forceps head includes: a forceps base; two forceps cups movably connected to one end of the forceps base; a pull rod disposed at the other end of the forceps base, and the pull rod is movably connected to the forceps cups; wherein, the pull rod is connected to the cable, and is configured to drive the two forceps cups to open and close under the traction of the cable.
[0022] In some embodiments, the endoscopic auxiliary diagnosis and treatment device is a biopsy forceps or a foreign body forceps. Description of the Drawings

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.
[0031] As Figure 1 and Figure 2 shown, according to an embodiment of the present utility model, an endoscopic assisted diagnosis and treatment device 100 is provided, including a forceps head 110 and a handle 120. The handle 120 is disposed on one side of the forceps head 110. The endoscopic assisted diagnosis and treatment device 100 further includes an outer tube 130. One end of the outer tube 130 is connected to the forceps head 110, and the other end of the outer tube 130 is connected to the handle 120. The outer tube 130 includes an inner layer 131 and an outer layer 132 covering the outside of the inner layer 131. The inner layer 131 is a flexible tube, and the outer layer 132 is adapted to tightly wrap the inner layer 131 and transmit the torque applied to the handle 120 to the forceps head 110.
[0032] The endoscopic assisted diagnosis and treatment device 100 in this embodiment is a biopsy forceps or a foreign body forceps. Among them, the forceps head 110 can be used to cut living tissue for sampling, and the handle 120 is used for the operator to hold, so as to control the movement of the forceps head 110.
[0033] The inner layer 131 of the outer tube 130 is a flexible tube. By adding the outer layer 132 covering the outside of the inner layer 131, the outer layer 132 tightly wraps the inner layer 131 and restricts the torque of the inner layer 131 itself. When the operator rotates the handle 120, the torque applied to the handle 120 can be accurately transmitted to the forceps head 110 without being affected by the torque of the inner layer 131 itself, improving the torque transmission performance of the outer tube 130, so that the forceps head 110 can rotate following the rotation of the handle 120. Furthermore, when the operator operates the handle 120 on the outside, the rotation angle of the forceps head 110 can be ensured to accurately sample the living tissue.
[0034] Specifically, when the handle 120 rotates, since the outer tube 130 is connected to the handle 120, the outer layer 132 of the outer tube 130 can transmit the torque when the handle 120 rotates to the forceps head 110 connected to the outer tube 130. Thus, the outer tube 130, the forceps head 110 and the handle 120 rotate synchronously, enabling the forceps head 110 to rotate to the required angle for sampling.
[0035] The flexible tube in this embodiment is a spring tube to better adapt to human organs, such as the curved intestine, which can facilitate the entry of the endoscopic assisted diagnosis and treatment device 100 into the human body. At the same time, the spring tube, as the inner layer 131 of the outer tube 130, can play a certain role in strengthening the internal cable. As an alternative embodiment, the flexible tube can also be a corrugated tube made of an elastic material, a spiral PU tube, etc.
[0036] The flexible tube and the handle 120 can rotate coaxially, which can ensure that the rotation of the handle 120 will not affect the flexible tube, thus suppressing the bending, winding, twisting, etc. of the flexible tube. Therefore, the reliability of the rotation of the forceps head 110 following the rotation of the handle 120 can be improved.
[0037] In this embodiment, the outer layer 132 is wound around the outer surface of the inner layer 131, which can better tightly wrap the inner layer 131, limit the torque of the inner layer 131 itself, and thus improve the torque transmission ability of the outer tube 130.
[0038] As Figure 2 shown, the outer layer 132 is a tubular structure formed by winding a hard material around the inner layer 131. The outer layer 132 of the outer tube 130 is made of a hard material wound around the outer wall of the inner layer 131, which is more convenient for the outer tube 130 to transmit the torque of the handle 120 to the clamp head 110. The outer layer 132 made of a hard material is wound around the inner layer 131 to form a tubular structure, so that the outer layer 132 can cover the inner layer 131 from the outside, and the inner layer 131 and the outer layer 132 form an integral body. This makes the whole outer tube 130 have a certain flexibility due to the existence of the inner layer 131, which is convenient for entering the human body. At the same time, the outer layer 132 ensures the torque transmission ability from the handle 120 to the clamp head 110.
[0039] Specifically, in this embodiment, the hard material forming the outer layer 132 is a metal wire. As an alternative embodiment, the hard material forming the outer layer 132 can also be plastic, or the hard material forming the outer layer 132 can be other materials as long as it can be wound around the inner layer 131.
[0040] Furthermore, the outer layer 132 has a mesh structure. The metal wire is wound around the outer wall of the inner layer 131 in a mesh structure, so that the outer layer 132 forms a metal braided mesh layer. In this way, after transmitting different torques, it is not easy to deform, which can extend the service life of the outer tube 130. Moreover, the outer layer 132 can also avoid some losses caused by collision and cutting, ensuring the overall service life of the endoscopic auxiliary diagnosis and treatment device 100.
[0041] As Figure 3 shown, the endoscopic auxiliary diagnosis and treatment device 100 further includes a protective tube 133, and the protective tube 133 is sleeved outside the outer tube 130.
[0042] Specifically, the material of the protective tube 133 can be plastic, so that the protective tube 133 forms a plastic-coated layer. The protective tube 133 can play a certain protective role for the outer tube 130, further extending the service life of the outer tube 130. At the same time, it can protect the endoscopic auxiliary diagnosis and treatment device 100 from being easily worn by the outside.
[0043] The endoscopic auxiliary diagnosis and treatment device 100 further includes a sliding member 140 and a cable 150. The sliding member 140 is connected to the handle 120 along the length direction of the handle 120 for the operator to slide. The inner layer 131 encloses an avoidance space that can penetrate along the length direction. The cable 150 is threaded through the avoidance space, and one end of the cable 150 is connected to the forceps head 110, and the other end of the cable 150 is connected to the sliding member 140. By connecting the sliding member 140 and the forceps head 110 through the cable 150, the operator can slide the sliding member 140 on the outside to control the opening and closing of the forceps head 110, and the operation is relatively convenient.
[0044] As Figure 3 shown, the endoscopic auxiliary diagnosis and treatment device 100 includes a forceps head 110, an outer tube 130, a handle 120, a sliding member 140, and a cable 150. The cable 150 can be used as a traction member. For example, the cable 150 is a traction wire.
[0045] The handle 120 includes a main body portion and an operation portion. The operation portion is provided at one end of the main body portion close to the operator. The operation portion can be a circular ring portion; the main body portion is generally a cylindrical rod, and the sliding member 140 can slide along the axial direction of the main body portion of the handle 120.
[0046] In some embodiments, the sliding member 140 can be a slip ring. The sliding member 140 includes two ring structures and a connecting structure provided between the two ring structures. The two ring structures are for the operator to operate, and the connecting structure is sleeved outside the main body portion of the handle 120, and the shape of the connecting structure matches the shape of the main body portion. For example, when the main body portion of the handle 120 is a rod with a circular cross-section, the connecting structure of the sliding member 140 can also be a rod with a circular cross-section.
[0047] A through hole is provided in the connecting structure, and the main body portion of the handle 120 is passed through the through hole. The diameter of the through hole is the same as or slightly larger than the outer diameter of the main body portion of the handle 120. The sliding member 140 can be sleeved outside the handle 120 through this through hole and can slide along the axial direction of the handle 120.
[0048] The sliding member 140 can only slide along the axial direction of the handle 120 and cannot rotate circumferentially relative to the handle 120. Therefore, when the handle 120 rotates circumferentially, the sliding member 140 also rotates circumferentially with the handle 120. Since the sliding member 140 is fixed to the cable 150, and the cable 150 is connected to the forceps head 110, when the sliding member 140 rotates, it can drive the cable 150 and the forceps head 110 to rotate together.
[0049] As Figure 4As shown, the pliers head 110 includes: a pliers base 111, two pliers cups 112 and a pull rod 113. The pliers cups 112 are movably connected to one end of the pliers base 111, the pull rod 113 is arranged at the other end of the pliers base 111, and the pull rod 113 is movably connected to the pliers cups 112. Among them, the pull rod 113 is connected to the cable 150, and is used to drive the two pliers cups 112 to open and close under the traction of the cable 150.
[0050] The two pliers cups 112 are connected to one end of the cable 150 through a connecting piece, and are installed on the pliers base 111 in a manner that can be opened and closed when being pulled by the cable 150.
[0051] Obviously, the above embodiments are only examples given for clear illustration, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
