Description

Technical Field

[0001] This utility model relates to the field of suture needle testing technology, specifically a suture needle elasticity and toughness tester. Background Technology

[0002] Medical sutures are critical consumables in surgical procedures. Their elasticity and toughness directly affect surgical safety and suturing effectiveness, and must strictly comply with the YY / T 0043-2016 standard for "Medical Sutures". Most existing suture elasticity and toughness testing equipment applies a horizontal force to the suture using an electric pusher, causing it to deform. In elasticity testing, force is applied to the suture via the pusher device, unfolding it into a specified arc, and the deformation is measured based on the rebound value; the deformation should conform to the standard value. In toughness testing, force is applied to the suture via the pusher device, unfolding it to a standard arc, and then observing whether the suture breaks.

[0003] During the aforementioned toughness test, it is necessary to observe whether the suture needle breaks. This means that if the suture needle is not tough enough, it will break before bending to the standard arc during the test. After being pushed to the standard arc, the suture needle may break off directly. At this time, the broken part of the suture needle will splatter and is not easy to clean. The broken part may even bounce onto the sensor and slide rail, which may easily cause sensor damage and slide rail jamming. Utility Model Content

[0007] Furthermore, the suture needle adhesion structure includes a soft silicone pad and double-sided adhesive tape. The soft silicone pad is fixedly installed on the front baffle and the right baffle, and the double-sided adhesive tape is adhered to the soft silicone pad.

[0008] Furthermore, the elasticity testing component includes a connecting seat, a fixed seat, and a springback measuring structure. The fixed seat is fixedly installed on the top of the chassis. A fixed rail is fixedly installed on the right side of the fixed seat, and a sliding rail is slidably arranged on the right side of the fixed seat. A sewing needle clamp is fixedly installed at one end of the fixed rail and the sliding rail near the center of the fixed seat. The connecting seat is detachably mounted on the mounting seat.

Nuts are threadedly sleeved at both the upper and lower ends of the connecting rod. The springback measuring structure is located behind the fixed seat.

[0009] Furthermore, the rebound measurement structure includes a second fixed base and a push plate. The second fixed base is fixedly installed on the top of the chassis, and a first displacement sensor is fixedly installed on the second fixed base. The push plate is fixedly installed on the sliding rail, and the sensing end of the first displacement sensor is in contact with the rear end of the push plate.

[0010] Furthermore, the elastic element includes a sliding rod, the left end of which is fixedly connected to the right outer wall of the right side baffle. The sliding rod movably passes through the outer wall of the L-shaped baffle. A fixing plate is fixedly installed on the right end of the sliding rod, and a spring is fixedly installed on the left side of the fixing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The bottom baffle, right side baffle, L-shaped baffle, front baffle and top baffle form a cover with only a rear opening to cover the suture needle. Since the rear end of the suture needle is clamped by the suture needle clamp, when the suture needle breaks and splashes, it splashes to the right front. Therefore, the cover with only a rear opening can also effectively intercept the splashing suture needle and prevent the suture needle from splashing onto the sensor and electric slide rail. Suture needle adhesion structures are set on the right side baffle and the front baffle, which have a high probability of adhering to the splashed suture needle.

[0016] 2. Utilizing a soft and elastic silicone pad as the base structure, the soft silicone pad can buffer and absorb the kinetic energy of the scalpel when it hits the double-sided adhesive tape. This allows the double-sided adhesive tape to better adhere to the scalpel. The use of removable double-sided adhesive tape as the adhesion structure makes replacement more convenient. Each time a broken scalpel is removed, simply peel off the double-sided adhesive tape and then attach a new double-sided adhesive tape to the soft silicone pad. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figures 1-8 This utility model provides a technical solution: a suture needle elasticity and toughness tester, including a housing 1 and a suture needle clamp 10. A shell 3 is fixedly installed on the top of the housing 1, and a flip cover 4 is rotatably connected to the top of the shell 3. Shock-absorbing support feet 2 are fixedly installed at the four corners of the bottom of the housing 1. An electric slide rail 5 is fixedly installed on the top of the housing 1. A mounting base 6 is fixedly installed at the sliding end of the electric slide rail 5. An elasticity testing component 8 and a toughness testing component 9 are provided inside the shock-absorbing support feet 2.

[0028] The toughness testing assembly 9 includes a fixed base 3 901 and a push head 904. The fixed base 3 901 is fixedly installed on the top of the chassis 1. The left end of the push head 904 is detachably connected to the mounting base 1 6. The top of the fixed base 3 901 is detachably equipped with a mounting base 2 902. The front end of the mounting base 2 902 is detachably equipped with a maximum arc limiter 903. The top of the fixed base 3 901 is fixedly installed with a right side baffle 905. The top of the right side baffle 905 is slidably equipped with an L-shaped baffle 906. The bottom of the push head 904 is detachably connected to the mounting base 6. A bottom baffle 908 is installed, a front baffle 9010 is fixedly installed on the front of the bottom baffle 908, a top baffle 909 is fixedly installed on the top of the front baffle 9010, a right baffle 905 and an L-shaped baffle 906 are elastically connected by an elastic element 907, a suture needle adhesion structure 7 is fixedly installed on the back of the front baffle 9010 and the left side of the right baffle 905, and a suture needle clamp 10 is fixedly installed on the front of the mounting base 902. The suture needle clamp 10 on the mounting base 902... One end of the suture needle is clamped, and the motorized slide rail 5 moves the mounting base 6, which in turn moves the push head 904. During the movement of the push head 904, the bottom baffle 908 moves synchronously. The bottom baffle 908, located below the suture needle, catches any broken pieces of the needle. After the push head 904 contacts the suture needle, the bottom baffle 908, right side baffle 905, L-shaped baffle 906, front baffle 9010, and top baffle 909 form a cover with an opening only at the rear, enclosing the suture needle. Because the rear end of the suture needle is clamped by the suture needle clamp 10, when the suture needle breaks and splashes, it splashes to the right front. Therefore, the cover with only the rear opening can also effectively intercept the splashed suture needle, preventing the suture needle from splashing onto the sensor and the electric slide rail 5. Suture needle adhesion structure 7 is set on the right side baffle 905 and the front baffle 9010, which has a high probability of adhering to the splashed suture needle, making it convenient for the user to remove the suture needle. A maximum curvature limiter 903 is set to set the maximum bending curvature.

[0029] The suture needle adhesion structure 7 includes a soft silicone pad 701 and a double-sided adhesive tape 702. The soft silicone pad 701 is fixedly installed on the front baffle 9010 and the right baffle 905. The double-sided adhesive tape 702 is adhered to the soft silicone pad 701. Utilizing the soft and elastic soft silicone pad 701 as a base structure, when a splattered suture needle hits the double-sided adhesive tape 702, the soft silicone pad 701 can buffer and absorb the kinetic energy of the suture needle, thereby allowing the double-sided adhesive tape 702 to better adhere to the suture needle. The use of a tear-off double-sided adhesive tape 702 as the adhesion structure makes replacement more convenient. That is, each time a broken suture needle is removed, simply tear off the double-sided adhesive tape 702 and then adhere a new double-sided adhesive tape 702 to the soft silicone pad 701.

[0030] The elasticity testing assembly 8 includes a connecting seat 801, a fixed seat 804, and a springback measuring structure 807. The fixed seat 804 is fixedly installed on the top of the housing 1. A fixed rail 805 is fixedly installed on the right side of the fixed seat 804, and a sliding rail 806 is slidably arranged on the right side of the fixed seat 804. A sewing needle clamp 10 is fixedly installed at one end of both the fixed rail 805 and the sliding rail 806 near the center of the fixed seat 804. The connecting seat 801 is detachably mounted on the mounting seat 6. A connecting rod 802 is threadedly connected to the left end of the connecting seat 801. A push roller 803 is rotatably sleeved on the outer wall of the connecting rod 802. Nuts are threaded on both the upper and lower ends of the connecting rod 802. The springback measuring structure 807 is located behind the fixed seat 804 and is fixed by... The suture needle clamp 10 on the rail 805 and the sliding rail 806 clamps both ends of the suture needle. The operation of the electric sliding rail 5 causes the mounting seat 6 to move, which in turn drives the connecting seat 801 to move. The movement of the connecting seat 801 drives the connecting rod 802 to move, which in turn drives the push roller 803 to move. When the push roller 803 comes into contact with the suture needle, the suture needle will be deformed by force. When the electric sliding rail 5 works to reset the mounting seat 6, the push roller 803 will reset. The elasticity of the suture needle will push the sliding rail 806 to move. The elasticity of the suture needle is judged by detecting the displacement of the sliding rail 806 through the springback measuring structure 807. The connecting rod 802 connects the connecting seat 801 and the push roller 803, so that the push roller 803 can be replaced according to the size of the suture needle.

[0031] The springback measurement structure 807 includes a second fixed base 8071 and a pusher plate 8073. The second fixed base 8071 is fixedly installed on the top of the housing 1. A first displacement sensor 8072 is fixedly installed on the second fixed base 8071. The pusher plate 8073 is fixedly installed on the slide rail 806. The sensing end of the first displacement sensor 8072 is in contact with the rear end of the pusher plate 8073. The second fixed base 8071 is set up to install the first displacement sensor 8072. When the slide rail 806 is pushed and moved by the springback suture needle, the pusher plate 8073 moves synchronously. By measuring the amount of movement of the pusher plate 8073, the amount of movement of the slide rail 806 can be measured, and then the elasticity of the suture needle can be measured.

[0032] The elastic element 907 includes a slide rod 9071. The left end of the slide rod 9071 is fixedly connected to the right outer wall of the right side baffle 905. The slide rod 9071 movably passes through the outer wall of the L-shaped baffle 906. A fixing plate 9073 is fixedly installed on the right end of the slide rod 9071. A spring 9072 is fixedly installed on the left side of the fixing plate 9073. The left end of the spring 9072 abuts against the right outer wall of the L-shaped baffle 906. By using the slide rod 9071 to install the fixing plate 9073, the spring 9072 pushes the L-shaped baffle 906 to move to the left. When the L-shaped baffle 906 is forced to move to the right, it can compress the spring 9072.

[0033] The shock-absorbing support foot 2 includes a mounting cylinder 201, a hard rubber seat 202, and an insertion rod 203. The mounting cylinder 201 is fixedly installed at the bottom of the chassis 1. The insertion rod 203 is fixedly installed on the top of the hard rubber seat 202. The insertion rod 203 is inserted into the mounting cylinder 201. The insertion rod 203 is used to connect the mounting cylinder 201 and the hard rubber seat 202. The insertion method facilitates the replacement of worn or damaged hard rubber seat 202.

[0034] The front of the chassis 1 is fixedly mounted with a control panel 11 and a printer 12, and the printer 12 is set to print out the test structure;

[0035] A mounting rod 13 is fixedly connected between mounting base 1 (804) and mounting base 3 (901). Mounting base 3 (14) is slidably sleeved on the outer wall of mounting rod 13. Mounting base 3 (14) is fixedly mounted on mounting rod 13 by bolts. A displacement sensor 2 (15) is detachably installed on the top of mounting base 3 (14). The sensing end of displacement sensor 2 (15) faces mounting base 1 (6). The displacement sensor 2 (15) measures the movement distance of mounting base 1 (6) to avoid excessive movement of mounting base 1 (6), which could lead to excessive compression of the suture needle during the test and subsequent breakage.

[0036] Working principle: During the toughness test, first pull the L-shaped baffle 906 to the right. Then, use the suture needle clamp 10 on the mounting base 902 to clamp the rear end of the suture needle. After closing the flip cover 4, operate the control panel 11 to activate the electric slide rail 5, causing the mounting base 6 to move to the right, which in turn drives the push head 904 to move to the right, making the push head 904 contact the suture needle. Then, apply a horizontal force to the suture needle, increasing its bending arc until the set bending arc is reached. Then, operate the electric slide rail 5 to reset the mounting base 6. After opening the flip cover 4, pull the L-shaped baffle 906 to remove the suture needle, and then observe... Whether the suture needle breaks or disconnects, the bottom baffle 908 will move synchronously during the movement of the push head 904. The bottom baffle 908 is below the suture needle and can catch the broken suture needle. After the push head 904 contacts the suture needle, the bottom baffle 908, the right side baffle 905, the L-shaped baffle 906, the front baffle 9010 and the top baffle 909 form a cover with an opening only at the rear, which is used to catch the suture needle that splashes out due to disconnection. When performing the elasticity test, the front and rear ends of the suture needle are clamped by the suture needle clamps 10 on the fixed rail 805 and the sliding rail 806, respectively. Then the flip cover 4 is closed, and the electric sliding rail 5 is turned on through the control panel 11. The mounting base 6 moves to the right, which in turn moves the connecting base 801 to the right. The movement of the connecting base 801 moves the connecting rod 802, which in turn moves the push roller 803. After the push roller 803 contacts the suture needle, it applies a horizontal force to the suture needle, causing the bending arc of the suture needle to reach the set value. Then, the electric slide rail 5 moves the mounting base 6 back to its original position, which in turn moves the push roller 803 back to its original position. At this time, the elasticity of the suture needle will push the slide rail 806 to move, which in turn moves the push plate 8073. The displacement sensor 8072 detects the amount of movement of the push plate 8073, thereby testing the elasticity of the suture needle.

[0037] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
