Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a surgical marking device. Background Technology

[0002] Heart failure, or HF for short, is simply the inability of the heart to pump enough blood to maintain the body's circulation. According to statistics from the World Health Organization (WHO), approximately 15% to 20% of people will suffer from varying degrees of heart failure. Those over 65 years of age are hospitalized for heart failure, accounting for more than 50% of all hospitalizations, and the five-year mortality rate exceeds 50%. For heart failure patients, there are only three treatment options: conservative drug therapy, heart transplantation, and ventricular assist devices (VADs). Drug therapy is less effective, and heart transplantation is extremely difficult due to donor availability. Therefore, VADs are recognized worldwide as the most effective treatment for various stages of end-stage heart failure.

[0003] In cardiac surgery (ventricular assist device implantation surgery), a hole needs to be drilled at the apex of the heart to implant the ventricular assist device. Due to the size, shape and strength of the myocardium at the apex, the operation of drilling at the apex is relatively complicated and it is not easy to drill at the accurate implantation location.

[0004] Currently, the common procedure during surgery is to locate the ventricular suture ring, suture it first, and then drill the hole. This adds a suturing step between determining the ventricular suture ring location and drilling the hole. Due to errors during suturing, the actual ventricular suture ring location may deviate from the initially determined location, thus affecting the smooth progress of the surgery. Moreover, because the ventricular suture ring is sutured before drilling the hole, foreign objects generated during drilling are difficult to remove due to the obstruction of the ventricular suture ring.

[0005] Therefore, how to determine the drilling location and drill accurately, while thoroughly removing surrounding foreign objects, is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the object of the present invention is to provide a surgical marking device that can determine the drilling location and accurately drill holes during surgery, while fully removing surrounding foreign objects;

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A surgical marking device includes a surgical marking device body, wherein the surgical marking device body has a punching position marking hole for marking punching positions and a suture marking groove located outside the punching position marking hole for marking suture positions.

[0009] Optionally, in the above-mentioned surgical marking device, the punching position marking hole is used to mark the punching position by passing through a surgical suture, the surgical suture being a surgical suture that hooks onto the wall of the tissue or organ to be cut off.

[0010] Optionally, in the above-described surgical marking device, the suture marking groove is used to draw suture marking lines along the suture marking groove using a medical marking pen to mark the position of the suture line.

[0011] Optionally, in the above-described surgical marking device, each of the suture marking grooves is formed on a circumferential surface centered on the punching position marking hole, and extends radially from the circumferential surface toward the punching position marking hole. The suture marking grooves are evenly distributed on the circumferential surface, and each suture marking groove includes:

[0012] The first marking groove, and the suture marking line drawn along the first marking groove is the first suture marking line, which is used to mark the suture line position of the initial suture ventricular suture ring;

[0013] The second marking groove, and the suture marking line drawn along the second marking groove, is the second suture marking line, which is used to mark the position of the suture line of the final suture ventricular suture ring.

[0014] Optionally, in the above-described surgical marking device, the length of the first marking groove is greater than the length of the second marking groove;

[0015] And / or,

[0016] There are multiple first marking grooves, which are evenly distributed along the circumferential surface, and the second marking grooves are evenly disposed between two adjacent first marking grooves.

[0017] Optionally, in the above-mentioned surgical marking device, there are 4 first marking slots, and 1 or 2 second marking slots are provided between any two adjacent first marking slots.

[0018] Optionally, in the above-mentioned surgical marking device, the surgical marking device body is provided with a suture range marking groove. The suture range marking groove is located on the side of the suture line marking groove away from the punching position marking hole. The suture range marking groove is used to draw a marking range line along the suture range marking groove with a medical marking pen to mark the suture range.

[0019] Optionally, in the above-mentioned surgical marking device, the suture range marking groove includes multiple spaced suture range arc-shaped grooves, each of which is on the same circle with the punching position marking hole as the center, and any two adjacent suture range arc-shaped grooves are separated by a longitudinal beam.

[0020] Optionally, in the surgical marking device described above, the suture marking groove that coincides with the position of the longitudinal beam is arranged in the direction of the punching position marking hole to avoid the longitudinal beam.

[0021] Optionally, in the above-mentioned surgical marking device, the body of the surgical marking device is made of medical titanium alloy;

[0022] And / or,

[0023] One side surface of the surgical marking device body is a curved surface that fits into the wall of the tissue or organ;

[0024] And / or,

[0025] The surgical marking device has a chamfered edge on the side edge that fits against the tissue or organ wall.

[0026] The surgical marking device provided by this invention allows for the marking of sutures after the drilling positions have been determined on the tissue or organ wall. The device is then attached to the tissue or organ wall, and the marking hole is aligned with the determined drilling position. The drilling position is marked using the marking hole, and the suture marking groove is used to mark the suture position. After marking is completed, the surgical marking device can be removed, leaving the corresponding marks on the tissue or organ wall.

[0027] The marked perforation locations are then used to create holes in the tissue or organ wall using a surgical suture. After drilling, any foreign objects generated around the holes can be cleaned. Since the ventricular suture ring has not yet been sutured, the operator can thoroughly clean the area around the holes. After drilling, the ventricular suture ring is sutured along the marked suture lines, ensuring it adheres to the tissue or organ wall surface and is coaxial with the perforated holes.

[0028] This invention relates to the procedure of determining and drilling holes in the tissue or organ wall before suturing the ventricular suture ring. After drilling, the operator can thoroughly clean foreign objects around the holes. Furthermore, the pre-drilling and post-suturing approach makes it easier for the operator to ensure that the ventricular suture ring is coaxial with the holes in the tissue or organ wall, facilitating the implantation of ventricular assist devices. This invention greatly assists in the positioning of the ventricular suture ring and the suturing method during the surgical procedure. The device is simple and easy to use, simplifying the surgical procedure and improving surgical safety. Attached Figure Description

[0044] The core of this invention is to provide a surgical marking device to determine the drilling location and make accurate drilling, while also effectively removing surrounding foreign objects.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] like Figure 1 As shown, an embodiment of the present invention discloses a surgical marking device 100 for surgical procedures, including a surgical marking device body, on which a punching position marking hole 101 and a suture marking groove 102 are provided.

[0047] The punching position marking hole 101 is used to mark the punching position, and the suture marking groove 102 is located outside the punching position marking hole 101 and is used to mark the suture position. In surgery, the operator uses the surgical marking device to mark the punching and suture positions on the tissue organ wall 300 (in the case of heart surgery), then performs the punching operation, and finally sutures the ventricular suture ring 500.

[0048] like Figure 2 and Figure 3 As shown, the surgical marking device 100 provided by the present invention, after determining the drilling position on the tissue / organ wall 300, can be attached to the tissue / organ wall 300, and the drilling position marking hole 101 can be aligned with the determined drilling position. The determined drilling position can be marked through the drilling position marking hole 101, and the suture marking groove 102 can be used to mark the suture position. After the marking is completed, the surgical marking device 100 can be removed, leaving corresponding marks on the tissue / organ wall 300, such as... Figure 5 As shown.

[0049] The surgical marking device 100 is directly attached to the tissue / organ wall 300. In order to prevent the edges and corners of the surgical marking device 100 from damaging the tissue / organ wall 300, in a specific embodiment of the present invention, one side surface of the surgical marking device body is set as a curved surface that is attached to the tissue / organ wall 300, and the edge of the surgical marking device body that is attached to the tissue / organ wall 300 is chamfered.

[0050] Based on the markings made at the perforation locations, holes can be made in the tissue / organ wall 300 using a surgical burr tool 203. After perforation, any foreign matter generated around the holes can be cleaned. Since the ventricular suture ring 500 has not yet been sutured, the operator can thoroughly clean the foreign matter around the holes. After perforation, the ventricular suture ring 500 can be sutured along the markings made according to the suture line positions, ensuring that the ventricular suture ring 500 adheres to the surface of the tissue / organ wall 300 and is coaxial with the perforated holes.

[0051] This invention is used in the procedure of determining and drilling holes in the tissue / organ wall 300 before suturing the ventricular suture ring 500. After drilling, the operator can thoroughly clean foreign objects around the holes. Furthermore, the pre-drilling and post-suturing approach makes it easier for the operator to ensure that the ventricular suture ring 500 is coaxial with the holes drilled in the tissue / organ wall 300, facilitating the implantation of ventricular assist devices. This invention greatly assists in the positioning of the ventricular suture ring 500 and the suturing method during the surgical procedure. The device is simple and easy to use, simplifying the surgical procedure and improving surgical safety. Moreover, different specifications of surgical marking devices 100 can be designed for tissue / organ walls of different sizes, thus making it well-suited for surgery in adolescents and children.

[0052] There are many ways to mark the determined drilling position by marking the hole 101. For example, a medical marking pen 202 can be used to mark the tissue or organ wall 300. However, this method is not conducive to cleaning the tissue that has been cut off by drilling.

[0053] like Figures 2-4 As shown, to facilitate the cleaning of the removed tissue, in a specific embodiment of this invention, the determined punching positions can be marked using surgical sutures 201. For example, after determining the punching position on the tissue / organ wall 300, the operator can pass the surgical suture 201 through and hook it onto the tissue / organ wall 301 to be removed (i.e., the tissue at the punching position). When the surgical suture 201 passes through the tissue / organ wall 300, it should not penetrate it; it should pass through the middle layer and hook onto it. Then, the surgical marking device 100 is attached to the tissue / organ wall 300, and the surgical suture 201 is passed out through the punching position marking hole 101, so that the surgical marking device 100 is attached to the tissue / organ wall 300. One hand pulls the surgical suture 201 taut, and the other hand holds the surgical marking device 100 against it, so that the tissue / organ wall 300 and the surgical marking device 100 are tightly attached. Then, the suture position can be marked accordingly using the suture marking groove 102. Then the surgical marking device 100 is removed, leaving corresponding marks on the tissue / organ wall 300, such as... Figure 5 As shown.

[0054] like Figure 6As shown, after the surgical marking device 100 is taken out, the surgical piercing tool 203 is passed through the surgical suture 201 and makes a circular cut on the tissue organ wall 300, ensuring that the position hooked by the surgical suture 201 is located at the center of the circular cut by the surgical piercing tool 203, and that the diameter of the surgical piercing tool 203 is smaller than the range of the suture marking groove 102; after cutting, the cut tissue is pulled out through the surgical suture 201.

[0055] Those skilled in the art will understand that there are many methods for marking the position of the suture line through the suture marking groove 102. Any method that can mark the position of the suture line during surgery without causing damage to the tissues and organs can be used. In a specific embodiment of the present invention, the position of the suture line can be marked by drawing a suture marking line 401 along the suture marking groove 102 with a medical marking pen 202.

[0056] For example, after the operator pulls the surgical suture 201 taut with one hand and holds the surgical marking device 100 against the other, ensuring a tight fit between the tissue / organ wall 300 and the surgical marking device 100, the surgical assistant uses a medical marking pen 202 to draw a suture marking line 401 along the suture marking groove 102 to mark the suture position. In subsequent suturing operations, the operator can use the surgical suture 201 to suture the ventricular suture ring 500 according to the suture marking line 401 left by the medical marking pen 202 on the tissue / organ wall 300.

[0057] Furthermore, each suture marking groove 102 is formed on a circumferential surface centered on the punching position marking hole 101, and extends radially from the circumferential surface toward the punching position marking hole 101. To clarify the order in which the suture marking lines 401 are sutured during the suturing operation, the suture marking groove 102 can be divided into a first marking groove 1021 and a second marking groove 1022.

[0058] The suture marking line 401 drawn along the first marking groove 1021 is the first suture marking line 4011, which is used to mark the suture line position of the initial suture of the ventricular suture ring 500. It is sutured first during the suture operation to initially fix and position the ventricular suture ring 500.

[0059] The suture marking line 401 drawn along the second marking groove 1022 is the second suture marking line 4012. The second suture marking line 4012 is used to mark the suture line position of the final suture ventricular suture ring 500. The final suture operation is performed after the initial suture operation. The final suture can further suture the ventricular suture ring 500 after the initial suture to the tissue organ wall 300, so that the ventricular suture ring 500 is more closely connected to the tissue organ wall 300.

[0060] In order to initially position the ventricular suture ring 500 and the tissue / organ wall 300 together after the initial suturing and to evenly fix the ventricular suture ring 500 on the tissue / organ wall 300 after the final suturing, in a specific embodiment of the present invention, multiple first marking grooves 1021 are designed and evenly distributed along the circumferential surface, while second marking grooves 1022 are evenly arranged between two adjacent first marking grooves 1021.

[0061] During suturing, it is easier and faster for the operator to distinguish the first suture marking line 4011 and the second suture marking line 4012 drawn on the tissue / organ wall 300, which greatly facilitates the suturing process. For example, the first marking groove 1021 and the second marking groove 1022 can be designed with different shapes, so that the first suture marking line 4011 and the second suture marking line 4012 drawn along the first marking groove 1021 and the second marking groove 1022 have different shapes, making it easier for the operator to distinguish the suturing sequence. Alternatively, by setting the length of the first marking groove 1021 to be greater than the length of the second marking groove 1022, the first suture marking line 4011 and the second suture marking line 4012 drawn along the first marking groove 1021 and the second marking groove 1022 can be straight lines of different lengths, which also makes it easier for the operator to distinguish the suturing sequence.

[0062] In cardiac surgery (ventricular assist device implantation surgery), to better suture the ventricular suture ring 500, 8-12 stitches are typically used to achieve good suturing and sealing. Therefore, in a specific embodiment of the present invention, four first marking grooves 1021 can be set and evenly distributed along the circumference, i.e., the central angle formed by the line connecting any two adjacent first marking grooves 1021 and the punching position marking hole 101 is a right angle. One or two second marking grooves 1022 are evenly arranged between any two adjacent first marking grooves 1021. Suture marking lines 401 are drawn according to the suture marking grooves 102, and after the surgical marking device 100 is removed, corresponding marks are left on the tissue organ wall 300, such as... Figure 5 As shown.

[0063] Generally, the suture site will extend about 1 cm beyond the outer diameter of the suture ring. If it extends too far, when the surgical suture is tightened during suturing, the myocardial epithelium will bulge, causing the epithelium to become uneven and squeezing out the opening.

[0064] Based on this, the surgical marking device body disclosed in this embodiment may also be provided with a suture range marking groove 103. The suture range marking groove 103 is located on the side of the suture line marking groove 102 away from the punching position marking hole 101. During the marking process, the suture range of the surgical suture line 201 is marked by drawing a marking range line 402 along the suture range marking groove 103 with a medical marking pen 202.

[0065] During the suturing operation, the surgical suture 201 must not exceed the limit of the marking range line 402 to avoid skin bulging caused by the surgical suture 201 exceeding the outer diameter of the ventricular suture ring 500 by an excessive distance. During the marking process, after determining the punching position on the tissue / organ wall 300 with the surgical suture 201, the surgical marking device 100 is attached to the tissue / organ wall 300 by passing the surgical suture 201 through the punching position marking hole 101. The determined punching position is marked through the punching position marking hole 101, the suture position is marked through the suture marking groove 102, and the suture range marking groove 103 marks the suture range of the surgical suture 201. At this point, the marking process is complete, and the surgical marking device 100 can be removed for subsequent punching and suturing operations.

[0066] In a specific embodiment of the present invention, the suture range marking groove 103 is configured as a multi-segmented, spaced-apart arc-shaped suture range groove. Each arc-shaped suture range groove is located on the same circle centered on the punching position marking hole 101, and any two adjacent arc-shaped suture range grooves are separated by a longitudinal beam 104. Since the position of the longitudinal beam 104 may coincide with the position of the suture marking groove 102, and if they coincide, their positions will be connected, causing the longitudinal beam 104 to be unable to separate two adjacent arc-shaped suture range grooves 103, the suture marking groove 102 that coincides with the position of the longitudinal beam 104 is arranged towards the punching position marking hole 101 to avoid the longitudinal beam 104.

[0067] Because of its advantages such as light weight, corrosion resistance, non-ferromagnetic properties, non-toxicity, and good biocompatibility, medical titanium alloy is used as the material for the body of the surgical marking device in a specific embodiment of the present invention.

[0068] According to an embodiment of the present invention, the surgical procedure using the surgical marking device 100 can be divided into three steps: marking, punching, and suturing. Accurate marking requires first locating the desired punching position on the tissue / organ wall 300. In such cases... Figure 2 During the marking process, surgical suture 201 is passed through and hooked onto the perforation location on the tissue / organ wall 300. The curved side of the surgical marking device 100 faces the tissue / organ wall 300, and the surgical suture 201 is passed through the perforation marking hole 101, allowing the surgical marking device 100 to adhere to the tissue / organ wall 300. One hand pulls the surgical suture 201 taut, while the other hand holds the surgical marking device 100 against the tissue / organ wall 300 to ensure tight adhesion. The surgical assistant uses a medical marking pen 202 to draw the first suture marking line 4011 and the second suture marking line 4012 along the suture marking groove 102, and draws the marking range line 402 along the suture range marking groove 103. At this point, the marking process is complete. The surgical marking device 100 is removed, and the marking lines left on the tissue / organ wall 300 are as follows... Figure 5 As shown.

[0069] The drilling process is as follows Figure 6 As shown, the surgical puncture tool 203 is passed through the surgical suture 201 to make a circular cut in the tissue / organ wall 300, ensuring that the position where the surgical suture 201 is hooked is at the center of the circular cut by the surgical puncture tool 203, and that the diameter of the surgical puncture tool 203 is smaller than the range of the suture marking groove 102. After cutting, the cut tissue is pulled out through the surgical suture 201. At this point, the top view of the perforated tissue / organ wall 300 is as follows. Figure 7 As shown.

[0070] Finally, as Figure 8 The procedure for suturing the ventricular suture ring 500 is shown. The position of the ventricular suture ring 500 is adjusted to ensure it is coaxial with the incision in the tissue / organ wall 300. Next, the ventricular suture ring 500 is sutured according to the suture marking line 401. Initial suturing is performed first along the first suture marking line 4011 to initially fix and position the ventricular suture ring 500. Then, the final suture is performed along the second suture marking line 4012. During suturing, if the surgical suture line 201 extends too far beyond the outer diameter of the ventricular suture ring 500, there is a risk of skin bulging. Therefore, to ensure the suturing effect, care must be taken to ensure the suturing range does not exceed the restriction area of ​​the marking line 402. In this way, the ventricular suture ring 500 is sutured to the tissue / organ wall 300, facilitating the subsequent implantation of a ventricular assist device.
