Description

Technical Field

[0001] The utility model relates to the technical field of surgical robots, and in particular to an isolation component, an endoscope mechanism and a surgical robot. Background Art

[0002] Surgical robots are widely used in the medical field. Surgical robots are usually equipped with an endoscope, which includes a handle and a barrel. The barrel is inserted into the patient's body to capture images of the surgical site for the doctor to view. During surgery, the operating space needs to be a sterile environment. The barrel of the endoscope can be disinfected before the operation. However, the handle of the endoscope has a complex structure and many internal electronic components. The end of the handle away from the barrel also needs to be electrically connected to the endoscope main unit via a cable, making the handle difficult to disassemble and clean. Therefore, before surgery, a sterile cover is usually used to cover the handle and cable of the endoscope. On the one hand, it can isolate bacteria, avoid harm to patients, and improve the safety of the operation. On the other hand, it can also prevent structures such as the handle and cable from coming into contact with liquids and other substances generated during the operation, ensuring the durability of the endoscope and the surgical robot, and avoiding affecting the imaging effect of the endoscope, thereby ensuring the safety of the operation.

[0003] In the prior art, the sterile cover covering the handle is typically cylindrical with two open ends. One end of the sterile cover extends over the cable. Two lugs are formed on the other end of the sterile cover. Before surgery, the operator needs to cross-wrap the two lugs around the connection between the handle and the endoscope barrel and tie the two lugs together to secure the sterile cover to the endoscope. This complicates preoperative preparations and the lugs may come loose during surgery, failing to maintain sterile isolation and compromising surgical safety.

[0004] Based on this, there is an urgent need for an isolation component, an endoscope mechanism and a surgical robot to solve the problems mentioned above. Utility Model Content

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0039] This embodiment provides a surgical robot. Specifically, the surgical robot includes an endoscope mechanism. Figure 1-Figure 5As shown, the endoscope mechanism includes an endoscope 10, a mounting base 20, and an isolation assembly. The mounting base 20 is used to mount the endoscope 10. When the endoscope 10 is mounted on the mounting base 20, the lens barrel 101 of the endoscope 10 passes through the mounting base 20 along a first direction, and one end of the lens barrel 101 extends out of the mounting base 20 and is connected to the handle 102 of the endoscope 10. The isolation assembly is used to isolate the handle 102 of the endoscope 10 mounted on the mounting base 20.

[0040] In this embodiment, the mounting base 20 is a rectangular parallelepiped, and the first direction is the thickness direction of the mounting base 20. For ease of description, the second direction and the third direction are defined as being perpendicular to each other. It is assumed that after the endoscope 10 is mounted on the mounting base 20, the handle 102 of the endoscope 10 is located on one side of the first end surface 201 of the mounting base 20, that is, the first end surface 201 of the mounting base 20 is positioned toward the handle 102. The first direction is perpendicular to the first end surface 201. The second direction and the third direction are the width and length of the first end surface 201, respectively.

[0041] The surgical robot also includes a patient surgical end, which is equipped with several surgical operating arms, each of which is equipped with a drive seat. The drive seat is detachably equipped with an adapter. The mounting seat 20 is detachably connected to the adapter and is located on the side of the adapter away from the drive seat, that is, the adapter is disposed between the drive seat and the mounting seat 20. The adapter is located on the side of the mounting seat 20 opposite to the first end surface 201.

[0042] Preferably, the isolation assembly includes a connecting ring 1 and a sterile cover 2. A first connecting portion 3 is provided on the connecting ring 1, and a second connecting portion 4 is provided on the mounting seat 20. The first connecting portion 3 can be engaged with the second connecting portion 4 to achieve a detachable connection between the connecting ring 1 and the mounting seat 20. The sterile cover 2 is in the shape of a tube with openings at both ends, and the opening at one end of the sterile cover 2 is circumferentially sealed and connected to the connecting ring 1. When the endoscope 10 and the connecting ring 1 are both installed on the mounting seat 20, the end face of one end of the connecting ring 1 fits with the end face of one end of the mounting seat 20, the sterile cover 2 is sleeved on the handle 102, and the end of the sterile cover 2 away from the connecting ring 1 extends along the axial direction of the handle 102 and is sleeved on the cable 103, and the end of the barrel 101 of the endoscope 10 away from the handle 102 passes through the connecting ring 1.

[0043] This embodiment provides an isolation assembly, which includes a connecting ring 1 and a sterile cover 2. The sterile cover 2 is mounted on the mounting seat 20 by snapping the connecting ring 1. The installation process of the sterile cover 2 is relatively simple, thereby simplifying the operation of preoperative preparation, improving the convenience and efficiency of preoperative preparation, and helping to relieve the fatigue of the operator. In addition, the end face of the connecting ring 1 fits the end face of the mounting seat 20, ensuring the bacteria isolation function of the isolation assembly and improving the safety of the operation.

[0044] This embodiment provides an endoscope mechanism, which includes the above-mentioned isolation component, simplifies the installation process of the sterile cover 2, improves the operational convenience and efficiency of preoperative preparation, and ensures the bacteria isolation effect of the isolation component, thereby improving the safety of the operation.

[0045] This embodiment provides a surgical robot, which includes the above-mentioned endoscope mechanism, improves the operational convenience and efficiency of preoperative preparation, ensures the antibacterial effect, and improves the safety of the operation.

[0046] In this embodiment, the axis of the connecting ring 1 is arranged along the first direction. In other embodiments, the axis of the connecting ring 1 can also be arranged obliquely to the first direction, which is not limited here.

[0047] In this embodiment, the sterile cover 2 is made of a soft plastic material, such as polyethylene or TPU. The connecting ring 1 is made of a plastic material. The connecting ring 1 and the sterile cover 2 can be sealed using glue, or by heat pressing, ultrasonic welding, high-frequency welding, or other methods. In other embodiments, the materials of the sterile cover 2, the connecting ring 1, and the connection method between the sterile cover 2 and the connecting ring 1 can be adaptively selected and are not limited here.

[0048] As a preferred embodiment, one of the first connecting portion 3 and the second connecting portion 4 is a resilient claw with a protrusion 31 protruding from the resilient claw. The other of the first connecting portion 3 and the second connecting portion 4 is a slot recessed in the sidewall of the mounting base 20 or the connecting ring 1, and the protrusion 31 can be engaged or disengaged from the slot. The resilient claw and the slot provide a detachable connection between the connecting ring 1 and the mounting base 20, simplifying assembly and disassembly between the connecting ring 1 and the mounting base 20, further improving the efficiency of preoperative preparation, simplifying the structure of the connecting ring 1 and the mounting base 20, facilitating production and processing, and reducing manufacturing costs.

[0049] In this embodiment, when the endoscope 10 and the isolation assembly are both mounted on the mounting base 20, the connecting ring 1, the sterile cover 2, and the handle 102 are all disposed on the same side of the mounting base 20. The end surface of the connecting ring 1 can be in contact with the first end surface 201 of the mounting base 20. In other embodiments, the connecting ring 1 and the handle 102 can also be disposed on opposite sides of the mounting base 20 along the first direction, in which case the sterile cover 2 simultaneously covers the mounting base 20 and the handle 102. This is not a limitation herein.

[0050] It is understandable that, to ensure the sterile cover 2 is effective, it can only be used once. Therefore, the connecting ring 1 fixedly connected to the sterile cover 2 is also disposable. The mounting base 20 is relatively expensive and typically needs to be sterilized and used multiple times. During the process of the elastic claw being engaged in the slot, the elastic claw undergoes a certain degree of deformation, and is more likely to be deformed or damaged after repeated use. Specifically, the first connecting portion 3 is an elastic claw, one end of which is connected to the outer wall of the connecting ring 1, and the other end of the elastic claw is provided with a latching protrusion 31. The second connecting portion 4 is a slot, which is provided on the side wall of the mounting base 20. By arranging the elastic claw on the connecting ring 1, the elastic claw can be replaced together with the connecting ring 1 after the operation is completed. This avoids deformation or damage caused by repeated use of the elastic claw, ensures that the connecting ring 1 is securely engaged with the mounting base 2, and thus ensures that the end face of the connecting ring 1 and the end face of the mounting base 20 are securely aligned, thereby ensuring the sterile effect of the isolation assembly, improving surgical safety, and reducing maintenance costs.

[0051] In this embodiment, the elastic claw is made of the same material as the connecting ring 1 and is integrally formed. One end of the elastic claw is connected to the outer wall of the connecting ring 1, and the other end of the elastic claw extends away from the handle 102 and is provided with a latching protrusion 31.

[0052] As a preferred embodiment, the connecting ring 1 includes an integrally formed first ring body 11 and a second ring body 12. The first and second ring bodies 11 and 12 are arranged axially, i.e., one end of the second ring body 12 is sealedly connected to the first ring body 11. The end surface of the other end of the second ring body 12 is configured to mate with the end surface of the mounting seat 20. i.e., the first ring body 11 is connected to the end of the second ring body 12 that is distal to the mounting seat 20 in the first direction. The sidewall of the elastic claw is connected to the outer wall of the first ring body 11. The elastic claw is located outside the second ring body 12 and spaced apart from the outer wall of the second ring body 12. This arrangement reduces the connection area between the elastic claw and the connecting ring 1, facilitates elastic deformation of the elastic claw, ensures that the connecting ring 1 can be engaged with the mounting seat 20, and reduces the operating force required to deform the elastic claw, further alleviating operator fatigue. In this embodiment, the elastic claw is connected to the sidewall of the first ring body 11 and is provided with the aforementioned latching protrusion 31. In order to avoid the elastic claws, the sterile cover 2 in this embodiment is connected to the inner side wall of the connecting ring 1 or the end surface of the connecting ring 1 away from the mounting seat 20 .

[0053] Furthermore, the inner sidewall of the first ring body 11 is flush with the inner sidewall of the second ring body 12 along the circumferential direction, and the outer sidewall of the first ring body 11 is circumferentially protruding from the outer sidewall of the second ring body 12, so that the elastic claws are spaced apart from the sidewall of the second ring body 12. The above arrangement simplifies the structure of the connecting ring 1 and facilitates production and processing.

[0054] In this embodiment, the connecting ring 1 is rectangular, that is, the first ring body 11 and the second ring body 12 are also rectangular. The width direction of the connecting ring 1 is the second direction, and the length direction of the connecting ring 1 is the third direction.

[0055] Preferably, at least two elastic claws are provided along the circumference of the connecting ring 1, and at least two retaining grooves are provided along the circumference of the sidewall of the mounting seat 20. The at least two elastic claws correspond to the at least two retaining grooves, ensuring that the connecting ring 1 is securely fastened to the mounting seat 20. This ensures that the end faces of the connecting ring 1 and the mounting seat 20 are securely aligned, thereby ensuring the isolation assembly's bacterial isolation function and enhancing surgical safety. In this embodiment, three elastic claws are provided. In other embodiments, the number of elastic claws can be selected adaptively and is not limited here.

[0056] Preferably, at least one elastic claw group is provided on the connecting ring 1, and the elastic claw group includes two elastic claws, and the two elastic claws in the same elastic claw group are arranged opposite each other along the length direction or the width direction of the first end surface 201. The above arrangement reduces the possibility of deflection of the connecting ring 1 after being installed on the mounting seat 20, ensures the reliable installation between the connecting ring 1 and the mounting seat 20, and also avoids the situation of extrusion interference between the connecting ring 1 and the endoscope 10, thereby ensuring the durability of the endoscope 10 and the connecting ring 1, and also prevents the endoscope 10 from being squeezed and deviated by the connecting ring 1, ensuring the reliable installation of the endoscope 10, thereby ensuring the safety of the operation.

[0057] In this embodiment, the connecting ring 1 is provided with a set of elastic claws. Two elastic claws within the set are positioned opposite each other along the second direction, defining the position of the connecting ring 1 along the second direction. One of the sidewalls of the mounting base 20 along the third direction serves as a positioning sidewall 202, which is designed to engage with the positioning structure on the adapter to achieve the installation and positioning of the mounting base 20. In addition to the two elastic claws within the set, another elastic claw on the connecting ring 1 is located on the side of the mounting base 20 opposite the positioning sidewall 202, defining the position of the connecting ring 1 along the third direction.

[0058] In this embodiment, the outer wall of the first ring body 11 has the same dimension along the second direction as the width dimension of the first end face 201 of the mounting seat 20, and the outer walls on both sides of the first ring body 11 along the second direction are respectively flush with the two side walls of the mounting seat 20 along the second direction. That is, when the connecting ring 1 is installed on the mounting seat 20, the elastic claws connected to the outer side of the first ring body 11 extend along the first direction. The dimension of the outer wall of the first ring body 11 along the third direction is smaller than the length dimension of the first end face 201 of the mounting seat 20, and the connecting ring 1 is located at the end of the mounting seat 20 away from the positioning side wall 202. The outer wall of the first ring body 11 on the side away from the positioning side wall 202 is flush with the side wall of the mounting seat 20 on the side away from the positioning side wall 202. The above arrangement allows the connecting ring 1 to be spaced apart from the positioning side wall 202 of the mounting seat 20 and the positioning structure on the adapter, thereby reserving operating space.

[0059] In some embodiments, an elastic isolation layer is provided on the end surface of the connecting ring 1 that is in contact with the mounting seat 20. When the end surface of the connecting ring 1 or the first end surface 201 is uneven, the elastic isolation layer can be elastically deformed, and the end surface of the connecting ring 1 can be in contact with the end surface of the mounting seat 20, further ensuring the isolation function of the isolation component, improving surgical safety, reducing the requirements for processing accuracy, facilitating production and processing, and helping to reduce production costs.

[0060] Similarly, an elastic isolation layer may be provided on the end face of the mounting seat 20 that is in contact with the connecting ring 1. If the end face of the connecting ring 1 or the first end face 201 is uneven, the end face of the connecting ring 1 can be in contact with the end face of the mounting seat 20 by providing an elastic isolation layer, thereby further ensuring the antibacterial effect of the isolation component, improving the safety of the operation, reducing the requirements for processing accuracy, facilitating production and processing, and helping to reduce production costs.

[0061] Specifically, the elastic isolation layer can be made of a relatively soft and elastic material such as TPU, rubber, silicone rubber, etc. The elastic isolation layer can be connected to the second ring body 12 of the connecting ring 1 by bonding, dipping or other processes.

[0062] In some embodiments, the hardness of the second ring body 12 is less than the hardness of the first ring body 11, so that the second ring body 12 can undergo elastic deformation. When the end face of the connecting ring 1 or the first end face 201 is uneven, the end face of the connecting ring 1 can also be fitted with the end face of the mounting seat 20, further ensuring the bacterial isolation effect of the isolation component, improving the safety of the operation, and reducing the requirements for processing accuracy, facilitating production and processing, and helping to reduce production costs.

[0063] In some embodiments, a ring groove is provided on the first end surface 201 of the mounting seat 20, and the end of the connecting ring 1 is positioned within the ring groove. This arrangement facilitates determining the installation position of the connecting ring 1. Furthermore, the placement of the end of the connecting ring 1 within the ring groove reduces the possibility of the connecting ring 1 rotating about the second or third direction, further ensuring a secure fit between the connecting ring 1 and the mounting seat 20, reducing the possibility of a gap between the connecting ring 1 and the mounting seat 20, and ensuring a bacteria-isolating effect.

[0064] The annular groove may be directly provided on the first end surface 201 ; or two annular structures may be protruding from the first end surface 201 , with one annular structure being sleeved on the outside of the other annular structure, and an annular groove being formed between the two annular structures, which is not limited here.

[0065] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
