It should be understood that the embodiments are provided so that the disclosure of the present application is complete and complete, and the ideas of the exemplary embodiments are sufficiently conveyed to those of ordinary skill in the art.

[0049] As Figure 1 andFigure 2 As shown, the present application provides a surgical robot 10 for remotely manipulating to complete surgery. The surgical robot 10 can include a control system 11, an imaging system 12 and a mechanical arm system 13, which can communicate with each other. The control system 11 is also called a doctor's console. The control system 11 has a display unit for showing the environment of surgical instruments or endoscopes, control mechanisms for the doctor to operate, armrests and the like. The display unit has a viewing window for the doctor to observe. The control mechanisms are configured to perform various actions corresponding to the actions of surgical instruments or endoscopes. The armrests are used to place the doctor's arms. In addition, there are other control switches on the doctor's console which are convenient for hands or feet to touch or press to perform various function operations to complete human-computer interaction.

[0050] The imaging system 12 has a display screen, an endoscope controller, system electronics, an image processor and the like. Thus, the internal organs of the patient can be more clearly presented to the operator.

[0051] The mechanical arm system 13 is provided beside the patient, and a surgical instrument or an endoscope is provided at the distal end thereof for various surgical operations on the patient. The mechanical arm system 13 can include at least one mechanical arm. The mechanical arm has a plurality of jointed arms, and adjacent two jointed arms are connected by a joint and relatively movable with a certain degree of freedom, so that the distal end of the mechanical arm can realize the movement with multiple degrees of freedom. The distal end of the mechanical arm is provided with an instrument support frame, and a surgical instrument is detachably mounted on the instrument support frame. An instrument driving module is provided on the instrument support frame to drive the surgical instrument to perform actions such as insertion, clamping, hooking, cutting and shoveling.

[0052] In some cases, with reference to Figure 2 , a single mechanical arm can include an adjusting arm 131, an operating arm 132 and a holding arm 133. A surgical instrument or an endoscope is detachably mounted on the holding arm 133. During surgery, part of the main pipeline and the wrist mechanism of the surgical instrument are inserted through the tissues of the chest, abdominal wall and the like to replace the human hand to perform surgery. Adjacent two connecting rods in the adjusting arm 131 are pivotally connected by a rotating joint. In addition, a rotating joint is also provided between the adjusting arm 131 and the operating arm 132 to realize the pivotable connection. Before operating the mechanical arm system 13 to perform surgery, the adjusting arm 131 needs to be operated to make the holding arm 133 reach a specified position, and then the rotating joint of the adjusting arm 131 is locked. During surgery, the operating arm 132 is remotely controlled to complete the surgical operation, and the rotating joint of the adjusting arm 131 is kept locked to prevent the connecting rods in the adjusting arm 131 from rotating relative to each other during surgery.

[0053] In an example, with reference to Figure 2The mechanical arm system 13 comprises a base 136. The base 136 is provided with a stand 134 and a handle 135. The stand 134 comprises at least one set of lifting mechanisms (not shown). For example, the stand 134 comprises four sets of lifting mechanisms, each set of lifting mechanisms corresponding to one mechanical arm. An operator can assist in moving the base 136 through the handle 135.

[0054] The anastomat 137 is a medical instrument used in surgical operations to replace traditional surgical suturing, mainly used for the separation, closure and suturing of various cavities and tissues of the human body. The anastomat 137 is used as an end effector and is arranged on the instrument holding arm 133. The anastomat 137 comprises a sharp beak structure, which can enter a narrow space to clamp an organ tissue, thereby assisting in suturing and other operations.

[0055] In the related art, the sharp beak structure of the anastomat is usually fixedly connected with the anvil, and is difficult to disassemble. When the sharp beak structure is not needed or needs to be replaced, the anastomat can only be replaced to meet the needs, which is inconvenient to use.

[0056] To solve the problems in the related art, the embodiments of the present application provide an anastomat which can meet the use function of the above surgical scene and has the characteristic of being convenient to disassemble. The anastomat is commonly used in general surgery, general thoracic surgery, urology, gynecology, hepatobiliary surgery and other clinical departments for the separation, closure and suturing of tissues.

[0057] As shown in FIG. 1, Figures 3-4 As shown in FIG. 1,

[0058] The stapler in this application has a first jaw 110 and a second jaw pivotally connected for clamping and suturing tissue positioned between the first jaw 110 and the second jaw. The second jaw is configured with a second jaw body 120 and a beak 200, which are detachably connected. When the beak 200 needs to be removed or replaced, only the beak 200 on the second jaw body 120 needs to be removed, without replacing the entire stapler, thereby improving efficiency.

[0059] For example, the stapler also includes an instrument shaft 100, the proximal end of the second jaw body 120 is connected to the instrument shaft 100, and the stapler is connected to a structure such as a holding arm through the structure of the instrument shaft 100.

[0060] The first jaw 110 is also provided with a staple cartridge 111, which is used to store staples. During operation, the staples in the staple cartridge 111 can be used for tissue suturing by pushing them out. Exemplarily, the first jaw 110, the second jaw body 120 and the instrument shaft 100 are pivotally connected by a connecting shaft mounted on the instrument shaft 100.

[0061] like Figure 5 The diagram shown is an exploded view of the beak and the second jaw in an embodiment of this application. The beak 200 has a proximal end that connects to the second jaw body 120, and a distal end that is a curved portion 210 inclined toward the first jaw. The curved portion 210 has a pointed structure, which can effectively clamp and position the tissue between the first jaw 110 and the second jaw. Exemplarily, the proximal end of the beak 200, i.e., the connecting portion, is detachably connected to the second jaw body 120 by a snap-fit ​​mechanism.

[0062] In some embodiments, the proximal end of the beak 200 (i.e., the end near the second jaw body 120) is provided with a receiving cavity, through which the beak 200 can be fitted onto the distal end of the second jaw body 120.

[0063] Exemplarily, the second jaw body 120 comprises a mounting portion 123 provided with a notch 122, the proximal end of the beak 200 is a connecting portion connected with the second jaw body 120, the connecting portion is provided with a receiving cavity 220, a connecting piece is arranged in the receiving cavity 220, and the connecting piece is embedded in the notch 122. In some embodiments, the connecting piece is an elastic piece. The notch 122 in the mounting portion 123 of the second jaw body 120 is used for cooperating with the connecting portion of the beak 200, the receiving cavity 220 is arranged on the connecting portion, and the elastic piece is arranged. After the elastic piece is embedded in the notch 122, the clamping connection between the second jaw body 120 and the beak 200 can be achieved, because the structure of the elastic piece itself has elasticity. When disassembly is needed, the beak 200 can be disassembled by separating the elastic piece and the notch 122, so that the replacement of the beak 200 is facilitated.

[0064] Exemplarily, the mounting portion 123 on the second jaw body 120 is located at the bottom of the second jaw body 120, the mounting groove 121 for accommodating at least part of the elastic piece is arranged on the mounting portion 123, and the notch 122 is arranged on the inner wall of the mounting groove 121. The notch 122 penetrates the inner wall of the mounting groove 121 to connect the inner and outer sides of the mounting groove 121. After the buckle 310 is embedded in the notch 122, the buckle 310 can be extruded at the notch 122 when disassembly of the beak 200 is needed, so as to separate the buckle 310 and the notch 122. It can be understood that the notch 122 here can also be a structure that does not penetrate the inner wall of the mounting groove 121, which can cooperate with the buckle 310 to achieve clamping connection.

[0065] The notch 122 is located on the inner wall of the bottom of the mounting groove 121. When the elastic piece and the notch 122 cooperate, the elastic piece is sent into the mounting groove 121, and then the elastic piece and the notch 122 are clamped, so as to realize the connection between the beak 200 and the second jaw body 120.

[0066] As shown in Figures 5-6 Exemplarily, the elastic piece comprises an elastic piece body 300 and a buckle 310 arranged at the first end of the elastic piece body 300, the second end of the elastic piece body 300 is arranged in the receiving cavity 220, and the buckle 310 is embedded in the notch 122. The second end of the elastic piece body 300 is arranged in the receiving cavity 220 to be connected with the connecting portion, the first end of the elastic piece body 300 is provided with the buckle 310, the buckle 310 is embedded in the notch 122 to cooperate with the mounting portion 123, and the detachable connection between the connecting portion and the mounting portion 123 is realized through the structure of the elastic piece body 300 and the buckle 310, so as to realize the detachable connection between the beak and the second jaw body 120.

[0067] The material of the elastic member includes, but is not limited to, metal or high-toughness polymer material, which has good elasticity and structural strength, so as to effectively connect the beak body 200 and the second jaw body 120 and ensure the connection strength, and also ensure a long service life of the elastic member body 300.

[0068] The buckle 310 includes a first bent portion 311 arranged at the first end of the elastic member body 300 and a second bent portion 312 arranged at the end of the first bent portion 311. The side of the first bent portion 311 away from the second bent portion 312 is in abutment with the first inner side wall of the notch 122, so as to connect the beak body 200 and the second jaw body 120. The second bent portion 312 extends towards the second inner side wall, which is arranged opposite to the first inner side wall. In some embodiments, the first bent portion 311 is perpendicular to the length direction of the elastic member body 300, and the second bent portion 312 is arranged obliquely relative to the first bent portion 311. When the buckle 310 and the notch 122 are matched, the first bent portion 311 is in abutment with the inner wall of the notch 122, so as to realize the clamping between the buckle 310 and the notch 122. The second bent portion 311 can be in abutment with the second side wall of the notch 122 after the buckle 310 and the notch 122 are matched, so that the connection between the buckle 310 and the second jaw body 120 is more stable.

[0069] In some embodiments, an inclined slope is arranged at the opening of the accommodating cavity 220, so as to form a space for avoiding the buckle 310. When the beak body 200 and the second jaw body 120 need to be assembled, the mounting portion 123 is connected with the accommodating cavity 220, and the buckle 310 at the end of the elastic member body 300 enters the mounting groove 121. Because the first bent portion 311 and the second bent portion 312 form the slope, the mounting portion 123 acts on the buckle 310 to make the buckle 310 deform, until the buckle 310 and the notch 122 are matched, so as to realize the assembly and connection.

[0070] When the beak body 200 and the second jaw body 120 need to be disassembled, a force away from each other can be applied to the beak body 200 and the second jaw body 120. Under the influence of the force, the inner side wall of the notch 122 acts on the buckle 310 to make the buckle 310 deform, and the space for avoiding the buckle 310 at the opening of the accommodating cavity 220 is used to cooperate with the deformed buckle 310 to separate from the notch 122, so as to facilitate the separation between the beak body 200 and the second jaw body 120.

[0071] In some embodiments, the second end of the elastic element body 300 is located in the receiving cavity 220 and is fixedly connected to the connecting portion by means of bonding or welding. Exemplarily, the second end of the elastic element body 300 is bonded to the inner wall of the receiving cavity 220 by means of adhesive or the like, or is fixed inside the receiving cavity 220 by welding, thereby achieving the connection.

[0072] like Figure 7 As shown, in some embodiments, the second end of the elastic element body 300 is located in the receiving cavity 220 and is detachably connected to the connecting part by a snap-fit ​​mechanism. Exemplarily, the second end of the elastic element body 300 is provided with a hook 320, and the connecting part has a mounting hole 230 communicating with the receiving cavity 220. The mounting hole 230 is located on the inner wall of the receiving cavity 220 on the side opposite to the second jaw body 120. A locking hole 240 is provided on the inner wall of the mounting hole 230 to engage with the hook 320. The hook 320 is embedded in the locking hole 240 to achieve the connection between the connecting part and the elastic element body 300. The locking hole 240 communicates with the receiving cavity 220 in the connecting part. The hook 320 is bent, with one end of the hook 320 located at the second end of the elastic element body 300, and the other end located in the locking hole 240 and abutting against the inner wall of the locking hole 240, thereby achieving the engagement between the hook 320 and the locking hole 240.

[0073] For example, the width of the mounting hole 230 and the locking hole 240 is smaller than the width of the receiving cavity 220. The locking hole 240, which is formed on the inner wall of the receiving cavity 220, connects the inner and outer sides of the mounting hole 230. The locking hook 320 can be pressed through the locking hole 240, causing the locking hook 320 to deform so that the locking hook 320 no longer abuts against the inner wall of the locking hole 240. This allows for separation between the locking hook 320 and the locking hole 240, enabling the disassembly of the elastic element body 300 and the connecting part. The detachable connection between the elastic element body 300 and the connecting part through the structure of the locking hook 320 facilitates the removal of the elastic element body 300 from the connecting part when disassembly is required, making it more convenient to use.

[0074] For example, the buckle 310 located at the first end of the elastic element body 300, the elastic element body 300, and the hook 320 located at the second end of the elastic element body 300 are integrally formed. In some embodiments, the buckle 310 and the hook 320 can also be fixed to the first end and the second end of the elastic element body 300 respectively by welding, bonding, or other methods.

[0075] The working mode of mounting and dismounting the sharp beak in the anastomat in the embodiment of the present application is described as follows: when the sharp beak needs to be mounted, the sharp beak body 200 and the second jaw body 120 are aligned, part of the elastic member enters the mounting portion 123 of the second jaw body 120, the elastic member enters the mounting groove 121 in the mounting portion 123 and finally cooperates with the notch 122, the buckle 310 at the first end of the elastic member body 300 is embedded in the notch 122, thereby realizing the connection between the sharp beak 200 and the second jaw body 120.

[0076] When dismounting is needed, opposite forces are applied to the second jaw body 120 and the sharp beak 200, the buckle 310 is deformed, so that the buckle 310 and the notch 122 are separated, thereby realizing the dismounting between the sharp beak 200 and the second jaw body 120. The buckle 310 can also be extruded by the bottom of the notch 122 to assist the deformation of the buckle 310, so as to realize the dismounting between the sharp beak 200 and the second jaw body 120.

[0077] The anastomat in the embodiment of the present application is characterized in that the proximal end of the second jaw body 120 and the first jaw 110 are pivotally connected, the distal end of the second jaw body 120 is provided with the sharp beak 200, the distal end of the sharp beak 200 is provided with the curved portion 210 for fixing the tissue to be clamped, and the distal end of the sharp beak 200 and the second jaw body 120 are detachably connected, so as to facilitate the dismounting and replacement of the sharp beak 200, thereby improving the efficiency.
