Description

Technical Field

[0001] This utility model relates to medical auxiliary equipment, specifically to a device for displaying the field of vision in assistive robotic surgery. Background Technology

[0002] Currently, most multi-arm surgical robots (robotic arm-assisted laparoscopic surgical systems) in clinical practice operate on a single arm with a single function. During surgery, revealing the surgical field requires the use of one arm, which not only wastes the robotic arm but also makes it impossible to effectively reveal the surgical field in emergencies such as massive bleeding, leading to the embarrassing situation of being unable to continue the surgery. Therefore, the invention of auxiliary devices for revealing the surgical field in robotic surgery is urgently needed. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model provides a device for assisting in the visualization of the surgical field in robotic surgery, which solves the limitations of the current clinical practice of relying solely on robotic surgical arm instruments to visualize the surgical field.

[0004] The technical solution of this utility model is: a device for assisting in the visualization of the surgical field in robotic surgery, comprising a restraint strap, wherein the restraint strap is a solid circular tube structure made of elastic material, and the restraint strap includes a head end, a body and a tail end along the central axis.

[0005] The constraint strap has a pointed end, and a head hook through hole is provided at the head end radially.

[0006] The restraint strap also has a pointed end, and the tail end of the restraint strap has a tail hook hole and a pointed end hole radially formed; the distance between the tail hook hole and the very end of the restraint strap is less than the distance between the pointed end hole and the very end of the restraint strap; when the tail hook hole is needed for hooking, the head end of the restraint strap can pass through the pointed end hole and drive the restraint strap body through the pointed end hole, and then be fixed by a buckle structure engaging with the pointed end hole. When the tail hook hole is not needed for hooking, the tail hook hole can be used as a spare pointed end hole.

[0007] The restraint strap body has multiple buckle structures evenly arranged on its surface along the central axis; the head end of the restraint strap can pass through the tip hole and drive the restraint strap body to pass through the tip hole, and then be fixed by the buckle structure cooperating with the tip hole.

[0008] It also includes hooks; both ends of the hooks are provided with claw structures, one end of which can hook into the hook hole at the head end or the hook hole at the tail end, and the other end of which can hook onto the abdominal wall.

[0009] Furthermore, the constraint band has multiple end hook holes evenly distributed along the central axis starting from the end of the constraint band.

[0010] Furthermore, the buckle structure is barbed.

[0011] Furthermore, the buckle structure is a ring-shaped protruding buckle.

[0012] Furthermore, the hook is an S-shaped hook.

[0013] Furthermore, one end of the hook has a single-claw structure that can hook into the hook hole at the head end or the hook hole at the tail end, while the other end has a multi-claw structure that can hook onto the abdominal wall. The multi-claw structure enhances the stability of the hook on the abdominal wall.

[0014] Furthermore, the overall length of the restraint strap is 15cm-20cm, and the diameter of the restraint strap body is 0.45cm-0.55cm.

[0015] Furthermore, the diameter of the tip perforation, the head hook perforation, and the tail hook perforation is 0.3cm-0.4cm.

[0016] The beneficial effects of this invention are: it provides a device for assisting in revealing the surgical field in robotic surgery, effectively overcoming the limitations of current clinical practice that relies solely on robotic surgical arm instruments for revealing the surgical field. By wrapping the head end of a restraint strap around the stomach and then passing it through a perforation at the tip, the device is fixed. Then, the hook at one end of the hook is engaged in a hook perforation (depending on the actual operation, it can be engaged in either the head or tail end hook perforation, or two hooks can be used, one in the head end and the other in the tail end hook perforation respectively), thus pulling the stomach back. Afterward, the other end of the hook is engaged in the abdominal wall to expose the abdominal cavity, avoiding interruptions to the surgery or requiring open surgery. This also shortens the surgical time and improves surgical efficiency and safety.

[0017] In addition, the device also has a hepatic hilum blocking function. By wrapping the end of the restraint band around the hepatic hilum and then passing the end of the restraint band through the tip perforation and continuing to extend to block the hepatic hilum, there is no need to place a separate hepatic hilum blocking device, making it a multi-purpose device.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] Example 1

[0027] A device for assisting in robotic surgery visualization includes, for example: Figure 1 The constraint band 1 shown and as follows Figure 2 Hook 5 is shown.

[0028] The restraint strap 1 is a solid circular tube structure made of elastic material, with an overall length of 18cm. Along its central axis, the restraint strap 1 includes a head end 2, a body, and a tail end 3. The head end 2 is pointed, and it has a 0.4cm head hook hole 7 radially formed. The tail end 3 is also pointed, and it has a 0.4cm tail hook hole 8 and a 0.4cm tip hole 6 radially formed. The distance between the tail hook hole 8 and the very end of the restraint strap is less than the distance between the tip hole 6 and the very end of the restraint strap. When the tail hook hole is needed for hooking, the head end of the restraint strap can pass through the tip hole, causing the body to pass through as well, and then be secured by a snap-fit ​​mechanism. When the tail hook hole is not needed for hooking, it can be used as a spare tip hole.

[0029] The restraint band body has multiple barbs 4 evenly distributed along its central axis on its surface (in actual use, no barbs are provided within a 4cm length of the head end of the restraint band body to prevent damage to blood vessels when used as a hepatic hilum occlusion). The diameter of the restraint band body is 0.5cm. The head end 2 of the restraint band can pass through the pointed perforation 6 and drive the restraint band body through the pointed perforation 6, where it is then fixed by the barbs 4 engaging with the pointed perforation.

[0030] The hook 5 is an S-shaped hook with claw structures at both ends. The claw at one end can hook into the hook hole 7 at the head end or the hook hole 8 at the tail end, and the claw at the other end can hook onto the abdominal wall.

[0031] This embodiment provides a device for assisting in revealing the surgical field of view in robotic surgery, which effectively overcomes the limitations of current clinical practice that relies solely on robotic surgical arm instruments for revealing the surgical field. For example... Figure 3 As shown, the restraint strap is wrapped around the stomach, then passed through a perforation at the tip and secured. The hook at one end is then hooked into a perforation (depending on the operation, this can be done at either the head or tail end, or two hooks can be used, one at the head and one at the tail end respectively), pulling the stomach back. The other end of the hook is then hooked onto the abdominal wall to expose the abdominal cavity, avoiding interruptions to the surgery or requiring open surgery. This also shortens the surgical time and improves surgical efficiency and safety.

[0032] In addition, the device also has a hepatic hilum blocking function. By wrapping the end of the restraint band around the hepatic hilum and then passing the end of the restraint band through the tip perforation and continuing to extend to block the hepatic hilum, there is no need to place a separate hepatic hilum blocking device, making it a multi-purpose device.

[0033] In addition, the device also has the function of suspending blood vessels, which can suspend separated arteries and veins, facilitating safe and rapid tissue dissection and freeing.

[0034] Example 2

[0035] The rest is the same as in Example 1, such as Figure 4 As shown, the constraint band 1 has multiple end hook holes 7 evenly spaced along its central axis, starting from the end 2 of the constraint band. In use, the hook at one end can be hooked into any of the end hook holes as needed. This makes it convenient to use.

[0036] Example 3

[0037] The rest is the same as in Embodiment 1 or 2, such as Figure 5 As shown, the restraint strap body has multiple annular protrusions 9 evenly arranged along the central axis on its surface (in actual use, no annular protrusions are provided within a 4cm length of the end of the restraint strap body to prevent the annular protrusions from tightening and damaging vascular tissue when used as a hepatic hilum block). The rounded protrusions and the pointed perforations work together to ensure reliable fixation.

[0038] Example 4

[0039] The rest is the same as any of the embodiments described in Examples 1-3, such as... Figure 6As shown, one end of the hook 5 has a single-claw structure that can hook into the hook hole, and the other end has a three-claw structure that can hook onto the abdominal wall. The multi-claw structure enhances the stability of the hook onto the abdominal wall.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
