Description

Technical Field

[0001] The invention relates to the technical field of surgical line fixing medical instruments, and in particular to a surgical line fixing structure and method for operating room nursing. Background Art

[0002] Surgical sutures refer to special sutures used for ligation and suture of hemostasis and tissue suture during surgical operations. They are mainly divided into absorbable sutures and non-absorbable sutures. The appropriate surgical sutures are selected according to the patient's surgical site. Traditionally, doctors hold needle holders and vascular clamps, but during long operations, the use of needle holders requires continuous force by the surgeon, which can easily cause hand fatigue and affect the accuracy of the operation. When clamping the vascular clamp, if the force is not applied properly, the surgical suture may be damaged, causing the suture to break or reduce its strength, affecting the suture effect.

[0003] Although existing surgical thread fixing structures can fix surgical threads, most of them are relatively simple in structure. After medical staff use scissors to cut the surgical threads, the cut part of the surgical threads will fall into the fixing structure, making it difficult for medical staff to remove the thread ends when using such surgical threads next time. This will undoubtedly prolong the operation process and increase the risk of the operation. At the same time, the surgical threads are exposed to the outside of the fixing structure after being cut, which can easily cause the surgical threads to be contaminated. To avoid this phenomenon, the front part of the surgical threads must be cut and discarded, resulting in a waste of resources. Summary of the invention

[0004] The purpose of the present invention is to solve the above existing technical problems and provide a surgical line fixing structure and method for operating room nursing, which can solve the technical problems of the existing surgical line cutting part falling into the fixing structure and making it difficult to remove the line when the surgical line is used next time, and the end of the surgical line is exposed and contaminated. The specific technical solution is as follows: A surgical line fixing structure for operating room nursing comprises a shell, a winding roller arranged in the shell, and a surgical line wound on the winding roller. A fixer, a guide roller, a disinfection roller group, a liquid storage chamber, a cutting and locking mechanism, and an electric wire feeding roller group are also arranged in the shell. A wire taking-out port is opened on the shell. The fixer is used to fix the winding roller. The surgical line output by the winding roller is input into the electric wire feeding roller group through the disinfection roller group after being folded by the guide roller. The surgical line output by the electric wire feeding roller group is output into the wire taking-out port after passing through the cutting and locking mechanism. The disinfection roller group comprises a movable roller and a fixed roller. The movable roller is arranged in the shell through a position adjustment mechanism. An infusion tube is connected to the outlet of the liquid storage chamber, and the outlet of the infusion tube is adapted to the position of the disinfection roller group.

[0005] Among them, the cutting lock wire mechanism includes a mounting block, a pressing piece, a driving column, a convex ring, a return spring, a locking piece and a sliding groove. The mounting block is fixed in the shell, and a first chamber and a second chamber are opened in the center of the mounting block. The first chamber is located above the second chamber and the two are connected up and down. The driving column is independently installed in the first chamber, and the upper end of the driving column extends out of the shell and is connected to the pressing piece. A convex ring is arranged on the upper part of the driving column. The return spring is sleeved on the driving column below the convex ring and the two ends are respectively abutted against the convex ring and the lower wall of the first chamber. A cutting component and a locking component are arranged in the second chamber. The lower end of the driving column extends into the second chamber and is connected to the cutting component and the locking component. The outer wall of the convex ring is connected to one end of the locking piece, and the other end of the locking piece is slidably limited in the sliding groove. The position of the driving column after moving up and down can be locked or unlocked through the cooperation of the locking piece and the sliding groove.

[0006] The lower end of the driving column is connected to a driving rod, and the driving column and the driving rod are connected in an inverted T shape, and the cutting component and the locking component are respectively connected to the two ends of the driving rod.

[0007] The cutting assembly includes a cutter and a cutter holder. The upper end of the cutter is detachably connected to the driving rod. The cutter holder is fixed in a second chamber directly below the cutter, and the upper part of the cutter holder has a notch that matches the cutter.

[0008] Among them, the locking assembly includes a connecting rod, an upper clamping piece, and a lower clamping piece. The upper end of the connecting rod is fixedly connected to the driving rod, the lower end of the connecting rod is connected to the upper clamping piece, and the lower clamping piece is fixed in a second chamber directly below the upper clamping piece. Anti-slip grooves are formed on the relative surfaces of the upper clamping piece and the lower clamping piece.

[0009] Among them, the sliding groove includes a common section, a first sliding section, a second sliding section, a third sliding section, and a fourth sliding section. The lower end of the first sliding section is connected to the third sliding section, the fourth sliding section in sequence, and then connected to the lower end of the second sliding section. The upper end of the first sliding section and the upper end of the second sliding section are both connected to the lower end of the common section, and an inverted V-shaped depression is formed between the third sliding section and the fourth sliding section. The locking member of the driving column is located in the common section in a natural state, and the locking member of the driving column is located in the inverted V-shaped depression when the driving column is in a position locked state. When the driving column is in a position unlocked state, the locking member resets and slides into the common section.

[0010] A driving assembly is fixed on the outer wall of the shell, and a sealing cover is connected to the driving end of the driving assembly through a connecting assembly, and the sealing cover can seal the wire taking port.

[0011] Among them, the disinfection roller group includes a movable roller and a fixed roller. The movable roller is arranged in the shell through a position adjustment mechanism. The position adjustment mechanism includes an adjusting knob, an adjusting screw, and a U-shaped connecting piece. The adjusting screw is passed through the shell, and one end of the screw located outside the shell is connected to the adjusting knob, and the other end of the screw located inside the shell is connected to the U-shaped connecting piece. The movable roller is fixed in the U-shaped connecting piece.

[0012] Among them, a length sensor for detecting the remaining amount of the surgical line is provided in the shell, a control mechanism is also provided in the shell, a warning light is provided on the top outer wall of the shell, the output end of the length sensor is electrically connected to the input end of the control mechanism, and the output end group of the control mechanism is connected to the input end of the warning light and the electric wire conveying roller group.

[0013] The present invention also provides a method for using the above-mentioned surgical line fixing structure for operating room nursing, comprising the following steps: Step 1, installing the winding roller wound with the surgical wire on the fixture in the housing; Step 2, lead the surgical wire in the winding roller, and pass it through the guide roller, the disinfection roller group, the electric wire conveying roller group, and the wire cutting and locking mechanism, and then insert it into the wire taking port; Step 3: Pull out the surgical thread from the thread removal port until the required length; Step 4: Press the thread cutting and locking mechanism to cut the surgical thread, and at the same time lock the end position of the surgical thread in the thread cutting and locking mechanism; Step 5: Press the wire cutting and locking mechanism again to unlock the end position of the surgical wire in the wire cutting and locking mechanism. At the same time, the electric wire feeding roller group is powered on to input the surgical wire into the wire taking port through the wire cutting and locking mechanism.

[0014] Among them, the specific steps of step 4 are as follows: when the pressing piece is pressed downward to drive the driving column to move downward, the locking piece moves downward synchronously with the driving column, and the lower end of the locking piece first slides out of the common section and slides to the connection between the first sliding section and the third sliding section at the lowest end. When the pressing piece loses the pressing force, the driving column will move upward under the action of the return spring, so that the lower end of the locking piece will move along the first sliding section to the inverted V-shaped depression formed between the third sliding section and the fourth sliding section. At this time, the position of the driving column will be locked, thereby locking the position of the surgical line through the cooperation of the upper clamping piece and the lower clamping piece of the locking assembly.

[0015] Among them, the specific steps of step 5 are as follows: when the pressing piece is pressed downward, the downward movement of the driving column will drive the locking piece to move downward synchronously, and the lower end of the locking piece will move from the inverted V-shaped depression formed between the third sliding section and the fourth sliding section to the connection between the second sliding section and the fourth sliding section. When the pressing piece loses the pressing force, the driving column will move upward under the action of the reset spring, and the lower end of the locking piece will reset and slide along the second sliding section to the common section, thereby unlocking the position of the driving column. After the position of the driving column is unlocked, the upper clamping piece of the locking assembly presses the lower clamping piece as the driving column moves upward, thereby unlocking the position of the surgical line.

[0016] Compared with the closest prior art, the technical solution provided by the present invention has the following beneficial effects: 1. The present invention can not only cut the surgical thread at the same time after one press by setting the cutting and locking mechanism, but also lock the position of the surgical thread. After pressing, the position of the surgical thread is unlocked and the surgical thread is conveyed for a certain distance through the electric wire conveying roller group so that the surgical thread extends from the cutting outlet to the wire taking-out port, thereby effectively overcoming the defect in the prior art that the surgical thread will fall into the fixed structure at the cutting point, making it difficult for medical staff to take out the thread ends of such surgical thread when using it next time, thereby prolonging the surgical process and increasing the risk of surgery; 2. The present invention can seal and protect the surgical thread at the thread taking port through the cooperation of the thread taking port, the driving component, the connecting component and the sealing cover, thereby effectively avoiding the defects of the prior art that the surgical thread is exposed after being cut, causing the surgical thread to be contaminated and waste resources; 3. The present invention detects the remaining amount of the surgical thread through a length sensor and indicates it through a warning light, and the limiting groove on the winding roller cooperates with the limiting protrusion on the fixture, so that the winding roller can be quickly replaced according to the remaining amount of the surgical thread; 4. The present invention can disinfect and keep the surgical thread moist through the cooperation of the disinfection roller group, the liquid storage chamber and the infusion tube, thereby avoiding the phenomenon that the surgical thread is dried to a certain extent and cannot meet the standard for wound suturing, thus causing medical accidents.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-6 .

[0021] An embodiment of the present invention provides a surgical line fixing structure for operating room nursing, comprising a shell 1, a winding roller 2 arranged in the shell 1, and a surgical line 3 wound on the winding roller 2. A fixer 4, a guide roller 5, a disinfection roller group 6, a liquid storage chamber 7, a cutting and locking wire mechanism 9 and an electric wire feeding roller group 19 are also arranged in the shell 1. A wire taking-out port 10 is opened on the shell 1. The fixer 4 is used to fix the winding roller 2. The surgical line 3 output by the winding roller 2 is input into the electric wire feeding roller group 19 after being folded by the guide roller 5. The surgical line 3 output by the electric wire feeding roller group 19 is output to the wire taking-out port 10 after passing through the cutting and locking wire mechanism 9. An infusion tube 8 is connected to the outlet of the liquid storage chamber 7, and the outlet of the infusion tube 8 is adapted to the position of the disinfection roller group 6.

[0022] It can be seen that this embodiment can not only cut the surgical thread 3 at the same time after one press, but also lock the position of the surgical thread 3, and can also unlock the position of the surgical thread 3 after this press and convey the surgical thread 3 for a distance through the electric wire conveying roller group 19 so that the surgical thread 3 extends from the cut-off point into the wire taking port 10, thereby effectively overcoming the defect in the prior art that the surgical thread 3 will fall into the fixed structure at the cut-off point, making it difficult for medical staff to remove the thread end when using such surgical thread next time, thereby prolonging the surgical process and increasing the surgical risk. At the same time, through the cooperation of the disinfection roller group 6, the liquid storage chamber 7, and the infusion tube 8, the surgical thread 3 can be disinfected and kept moist, avoiding the phenomenon that the surgical thread 3 is dried to a certain extent and cannot meet the standard for wound suturing, causing medical accidents.

[0023] from Figure 1 It can also be seen that a driving assembly 11 is fixed on the outer wall of the housing 1 , and a sealing cover 13 is connected to the driving end of the driving assembly 11 via a connecting assembly 12 , and the sealing cover 13 can seal the wire taking port 10 .

[0024] The present invention can seal and protect the surgical thread 3 located at the thread taking port 10 through the cooperation of the thread taking port 10, the driving component 11, the connecting component 12, and the sealing cover 13, thereby effectively avoiding the defects of the prior art that the surgical thread is exposed after being cut, causing the surgical thread to be contaminated and waste resources. Among them, the control of the driving component 11 can be achieved by a proximity sensor or a switch pressing method, and this embodiment does not make specific restrictions.

[0025] See attached Figure 1 A length sensor 15 for detecting the remaining amount of the surgical thread 3 is provided in the shell 1, a control mechanism 20 is also provided in the shell 1, and a warning light 16 is provided on the top outer wall of the shell 1. The output end of the length sensor 15 is electrically connected to the input end of the control mechanism 20, and the output end group of the control mechanism 20 is connected to the input end of the warning light 16 and the electric wire conveying roller group 19.

[0026] The remaining amount of the surgical thread 3 is detected by the length sensor 15 and indicated by the warning light 16, so that the winding roller 2 can be quickly replaced according to the remaining amount of the surgical thread 3. At the same time, the working state of the electric wire conveying roller group 19 driving component 11 can be controlled by the control mechanism 20, so as to better realize the delivery and taking of the surgical thread 3.

[0027] In the specific implementation, a line change cover 17 and a liquid adding cover 18 are also provided on the housing 1. The line change cover 17 covers the upper part of the holder 4, one side of which is hinged to the housing 1 and the other side is buckled with the housing 1; the liquid adding cover 18 covers the entrance of the liquid storage chamber 7, one side of which is hinged to the housing 1 and the other side is buckled with the housing 1. In the implementation, the line change cover 17 and the liquid adding cover 18 are both supported by a transparent acrylic plate, so as to facilitate the observation of the surgical line 3 and the remaining amount of disinfectant in the liquid storage chamber 7.

[0028] In this embodiment, by providing the wire replacement cover 17 and the liquid adding cover 18, the winding roller 2 and the disinfectant can be easily added and replaced, thereby improving the convenience of use of the present invention.

[0029] In the embodiment of the present invention, the specific structure of the thread cutting and locking mechanism 9 can be found in the attached Figure 3 -Attached Figure 5 , including a mounting block 901, a pressing member 904, a driving column 905, a convex ring 906, a reset spring 907, a locking member 908 and a sliding groove 9015, the mounting block 901 is fixed in the housing 1, a first chamber 902 and a second chamber 903 are provided in the center of the mounting block 901, the first chamber 902 is located above the second chamber 903 and the two are connected up and down, the driving column 905 is independently installed in the first chamber 902, the upper end of the driving column 905 extends out of the housing 1 and is connected to the pressing member 904, a convex ring 906 is provided on the upper part of the driving column 905, a reset spring 907, a locking member 908 and a sliding groove 9015 The spring 907 is sleeved on the driving column 905 below the convex ring 906 and its two ends are respectively abutted against the convex ring 906 and the lower wall of the first chamber 902. A cutting assembly and a locking assembly are arranged in the second chamber 903. The lower end of the driving column 905 extends into the second chamber 903 and is connected with the cutting assembly and the locking assembly. The outer wall of the convex ring 906 is connected to one end of the locking member 908, and the other end of the locking member 908 is slidably limited in the sliding groove 9015. The position of the driving column 905 after moving up and down can be locked or unlocked through the cooperation of the locking member 908 and the sliding groove 9015.

[0030] When the surgical thread 3 needs to be cut, the pressing piece 904 is pressed, and the pressing piece 904 will drive the driving column 905 to move downward, thereby cutting the surgical thread 3 through the cutting assembly; at the same time, due to the cooperation of the locking piece 908 and the sliding groove 9015, the driving column 905 will be locked after the pressing piece 904 loses pressure, so the locking assembly will continue to obtain pressure to lock the end position of the surgical thread 3 to prevent it from being transferred into the shell 1 and being contaminated or affecting its normal pulling out and use; when the pressing piece 904 is pressed again, the driving column 905 will be unlocked, and at this time the locking assembly loses pressure to unlock the position of the surgical thread 3, and at this time the electric wire transmission roller group 19 can normally drive the surgical thread 3 to be output to the wire removal port 10.

[0031] It can be seen that based on the structure of the above-mentioned cutting and locking wire mechanism 9, not only can the surgical wire 3 be cut at the same time after one press, but the position of the surgical wire 3 can also be locked, and the position of the surgical wire 3 can also be unlocked after this press and the surgical wire 3 can be transported for a certain distance through the electric wire conveying roller group 19 so that the surgical wire 3 extends from the cutting end into the wire removal port 10, thereby effectively overcoming the defect in the prior art that the surgical wire 3 will fall into the fixed structure at the cutting end, making it difficult for medical staff to remove the thread end when using such surgical wire next time, thereby prolonging the operation process and increasing the risk of surgery.

[0032] See attached Figure 2 and attached Figure 3 The lower end of the driving column 905 is connected to the driving rod 909, and the driving column 905 and the driving rod 909 are connected in an inverted T shape, and the cutting component and the locking component are respectively connected to the two ends of the driving rod 909.

[0033] Through the above-mentioned connection method, not only the fixed connection between the driving column 905 and the cutting component and the locking component is achieved, but it can also ensure that the driving column 905 can simultaneously drive the cutting component and the locking component to move synchronously, thereby ensuring that the cutting and locking line mechanism 9 can simultaneously achieve the cutting of the surgical thread 3 and the position locking of the surgical thread 3.

[0034] from Figure 3 It can also be seen that the cutting assembly includes a cutter 9010 and a cutter holder 9011. The upper end of the cutter 9010 is detachably connected to the drive rod 909. The cutter holder 9011 is fixed in the second chamber 903 directly below the cutter 9010, and the upper part of the cutter holder 9011 has a groove that matches the cutter 9010.

[0035] Through the above design, this embodiment can ensure that the surgical thread 3 can be completely cut through the cooperation of the cutter 9010 and the knife holder 9011.

[0036] like Figure 3 As shown, the locking assembly includes a connecting rod 9012, an upper clamping piece 9013, and a lower clamping piece 9014. The upper end of the connecting rod 9012 is fixedly connected to the driving rod 909, the lower end of the connecting rod 9012 is connected to the upper clamping piece 9013, and the lower clamping piece 9014 is fixed in the second chamber 903 directly below the upper clamping piece 9013. Anti-slip grooves are formed on the relative surfaces of the upper clamping piece 9013 and the lower clamping piece 9014.

[0037] Through the above-mentioned design, this embodiment can cooperate with each other through the cooperation of the upper clamping member 9013 and the lower clamping member 9014, and at the same time, anti-slip grooves are provided on the relative surfaces of the upper clamping member 9013 and the lower clamping member 9014. After the pressing member 904 is pressed down to cut the surgical thread 3, the position of the surgical thread 3 can be locked to prevent the surgical thread 3 from falling into the fixed structure or retracting into the winding roller 2 to affect the normal use of this structure.

[0038] See attached Figure 4 The sliding groove 9015 includes a common section 901501, a first sliding section 901502, a second sliding section 901503, a third sliding section 901504, and a fourth sliding section 901505. The lower end of the first sliding section 901502 is connected to the third sliding section 901504 and the fourth sliding section 901505 in sequence, and then connected to the lower end of the second sliding section 901503. The upper end of the first sliding section 901502 and the second sliding section 901503 are connected to each other. The upper ends of 503 are connected to the lower ends of the common sections 901501, and an inverted V-shaped depression is formed between the third sliding section 901504 and the fourth sliding section 901505. The locking member 908 of the driving column 905 is located in the common section 901501 in the natural state. The locking member 908 of the driving column 905 is located in the inverted V-shaped depression when the driving column 905 is in the position locked state. When the driving column 905 is in the position unlocked state, the locking member 908 resets and slides into the common section 901501.

[0039] Based on the above structure, when the pressing member 904 is pressed downward to drive the driving column 905 to move downward, the locking member 908 will move downward synchronously with the driving column 905. During this process, the lower end of the locking member 908 first slides out of the common section 901501 and slides to the connection between the first sliding section 901502 and the third sliding section 901504 at the lowest end. When the pressing member 904 loses the pressing force, the driving column 905 will move upward under the action of the return spring 907, so that the lower end of the locking member 908 will move along the first sliding section 901502 to the inverted V-shaped recess formed between the third sliding section 901504 and the fourth sliding section 901505. At this time, the position of the driving column 905 will be locked, that is, it can be locked by the locking group The pressing member 904 is used to lock the position of the surgical thread 3; if the pressing member 904 is pressed downward again, the downward movement of the driving column 905 will drive the locking member 908 to move downward synchronously, and the lower end of the locking member 908 will move from the inverted V-shaped depression formed between the third sliding section 901504 and the fourth sliding section 901505 to the connection between the second sliding section 901503 and the fourth sliding section 901505. When the pressing member 904 loses the pressing force, the driving column 905 will move upward under the action of the reset spring 907, and the lower end of the locking member 908 will reset and slide along the second sliding section 901503 to the common section 901501, thereby unlocking the position of the driving column 905, that is, controlling the locking assembly to unlock the position of the surgical thread 3.

[0040] It can be seen that the sliding groove 9015 and the locking piece 908 cooperate with each other, so that the wire cutting locking mechanism 9 forms a structure that is locked by pressing once and unlocked by pressing again, so that the position of the surgical line 3 is locked and unlocked based on such a design, and then cooperates with the electric wire transmission roller group 19, thereby overcoming the defect in the prior art that the surgical line 3 will fall into the fixed structure at the cut point, making it difficult for medical staff to remove the thread end when using such surgical line next time, thereby prolonging the operation process and increasing the risk of surgery.

[0041] See attached Figure 5 The disinfection roller group 6 includes a movable roller and a fixed roller. The movable roller is arranged in the shell 1 through a position adjustment mechanism 14. The position adjustment mechanism 14 includes an adjusting knob 1401, an adjusting screw 1402, and a U-shaped connecting piece 1403. The adjusting screw 1402 is passed through the shell 1, and one end of the adjusting screw 1402 located outside the shell 1 is connected to the adjusting knob 1401, and the other end of the adjusting screw 1402 located inside the shell 1 is connected to the U-shaped connecting piece 1403. The movable roller is fixed in the U-shaped connecting piece 1403.

[0042] In this embodiment, the position of the movable roller can be adjusted by the position adjustment mechanism 14, so as to adjust the amount of disinfectant soaked on the surgical thread 3, that is, to adjust the wetness of the surgical thread 3, so as to adapt to the needs of different usage scenarios.

[0043] like Figure 6 As shown, the fixture 4 is cylindrical, a limiting protrusion 401 is formed on the fixture 4, the winding roller 2 is annular, a limiting groove 201 is formed on the inner wall of the winding roller 2, and a key matching structure is formed by the limiting protrusion 401 and the limiting groove 201, so that the winding roller 2 can be quickly installed and fixed.

[0044] This embodiment also proposes a method for using the above structure, and the specific steps are as follows: Step 1: Open the wire replacement cover 17 and install the winding roller 2 wound with the surgical wire 3 on the holder 4 in the housing 1; Step 2: Lead the surgical wire 3 in the winding roller 2, pass it through the guide roller 5, the disinfection roller group 6, the electric wire conveying roller group 19, cut the wire locking mechanism 9, and then insert it into the wire taking port 10; Step 3: The control mechanism 20 controls the driving assembly 11 to rotate, so as to drive the sealing cover 13 to open the thread taking port 10 through the connecting assembly 12, and the medical staff pulls out the surgical thread 3 from the thread taking port 10 to the required length; Step 4: Press the thread cutting and locking mechanism 9 to cut the surgical thread 3, and at the same time lock the end position of the surgical thread 3 in the thread cutting and locking mechanism 9; In this step, when the pressing member 904 is pressed downward to drive the driving column 905 to move downward, the locking member 908 moves downward synchronously with the driving column 905, and the lower end of the locking member 908 first slides out of the common section 901501 and slides to the connection between the first sliding section 901502 and the third sliding section 901504 at the lowest end. When the pressing member 904 loses the pressing force, the driving column 905 will move upward under the action of the return spring 907, so that the lower end of the locking member 908 will move along the first sliding section 901502 to the inverted V-shaped depression formed between the third sliding section 901504 and the fourth sliding section 901505. At this time, the position of the driving column 905 will be locked, so that the position of the surgical thread 3 will be locked through the cooperation of the upper clamping member 9013 and the lower clamping member 9014 of the locking assembly; Step 5: Press the wire cutting and locking mechanism 9 again to unlock the end position of the surgical wire 3 in the wire cutting and locking mechanism 9, and at the same time, the control mechanism 20 controls the electric wire feeding roller group 19 to power on and input the surgical wire 3 into the wire taking port 10 through the wire cutting and locking mechanism 9; The specific movement process of this step is: when the pressing member 904 is pressed downward, the downward movement of the driving column 905 will drive the locking member 908 to move downward synchronously, and the lower end of the locking member 908 will move from the inverted V-shaped depression formed between the third sliding section 901504 and the fourth sliding section 901505 to the connection between the second sliding section 901503 and the fourth sliding section 901505. When the pressing member 904 loses the pressing force, the driving column 905 will move upward under the action of the reset spring 907, and the lower end of the locking member 908 will reset and slide along the second sliding section 901503 to the common section 901501, thereby unlocking the position of the driving column 905. After the position of the driving column 905 is unlocked, the upper clamping member 9013 of the locking assembly moves upward with the driving column 905 to press the lower clamping member 9014, thereby unlocking the position of the surgical thread 3. Step 6: The control mechanism 20 controls the driving assembly 11 to rotate, so as to drive the sealing cover 13 to seal and close the wire taking port 10 through the connecting assembly 12 .

[0045] During the above use, if the control mechanism 20 detects through the length sensor 15 (which may be an encoder or a photoelectric sensor) that the remaining amount of the surgical thread 3 is less than a preset threshold, a warning signal will be issued through the warning light 16, and the medical staff can replace the winding roller 2 with a new one by opening the thread replacement cover 17. In addition, when it is observed through the liquid filling cover 18 that the remaining amount of disinfectant in the liquid storage chamber 7 is not much, the liquid filling cover 18 can also be opened to add disinfectant into the liquid storage chamber 7.

[0046] In summary, the present invention not only effectively overcomes the defect in the prior art that the surgical thread 3 will fall into the fixed structure at the cut point, making it difficult for medical staff to remove the thread ends when using such surgical thread next time, thereby prolonging the surgical process and increasing the risk of surgery; at the same time, it effectively avoids the defect in the prior art that the surgical thread is exposed after being cut, causing the surgical thread to be contaminated and waste resources. In addition, the surgical thread 3 can be disinfected and kept moist, avoiding the phenomenon that the surgical thread 3 is dried to a certain extent and cannot meet the standard for wound suturing, causing medical accidents.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, a person skilled in the art can still modify or make equivalent substitutions to the specific implementations of the present invention. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention are within the scope of protection of the claims of the present invention to be approved.
