Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a tolerance curing fixture for medical devices. Background Technology

[0002] With the innovation and upgrading of medical surgical instruments, the demand for disposable high-frequency bipolar surgical electrodes in clinical surgical applications continues to grow. To meet market demand, the factory started to expand its production capacity. However, in the process of expanding production capacity, the product process defect rate also increased, causing unnecessary waste of funds for the factory and triggering a series of production and delivery problems.

[0003] In a disposable high-frequency bipolar surgical electrode, two jaw assemblies together form a target part with upper and lower jaws. After closure, the gap between the upper and lower jaws needs to meet the requirement of 0.06-0.16mm. The jaw assembly comprises four parts: a powder metallurgy part (hereinafter referred to as the "support"), a sintered ceramic part (hereinafter referred to as the "ceramic part"), an electrode sheet, and a positioning component. The support, ceramic part, and electrode sheet need to be bonded together with medical adhesive, and after drying and curing, they form a complete assembly unit. There are key process shortcomings in the production of the two parts made of different materials: the support and the ceramic part. During the final sintering and molding stage of the support and ceramic components, the material shrinkage rate is difficult to control precisely, making it impossible for suppliers to consistently guarantee the dimensional accuracy and tolerance of the products. Each product in the same batch has varying degrees of individual dimensional differences. This instability in the dimensions of each product leads to defects in the assembly process: after the upper and lower jaw components are closed, their gaps cannot meet the design standards, thus creating potential functional hazards in the product and causing abnormal tissue closure during clinical surgery, posing a significant surgical safety risk to patients. Due to the dimensional differences, the yield rate of finished products has long hovered between 35% and 40%, with a large number of semi-finished and finished products being scrapped due to assembly defects, resulting in serious material waste. To meet the demand for shipments, the production department has to repeatedly replenish materials and repeat assembly operations, leading to additional labor costs. This inefficient production cycle significantly prolongs the product delivery cycle.

[0004] Therefore, a new technical solution is needed to address the problems existing in the current technology. Utility Model Content

[0010] Preferably, the lever assembly further includes a translation component, the side wall of the locking position is provided with a horizontal groove, the tail shank of the bracket is provided with an oblique hole, when the electrode assembly is located below the bracket, the oblique hole is inclined downward from the side near the electrode assembly to the side near the tail shank of the bracket, and the conversion component is detachably connected to the tooling base and the jaw assembly by sequentially passing through the groove, the oblique hole and the conversion hole via the translation component.

[0011] Preferably, the lever assembly further includes a pivot shaft, and the side wall of the clamping position and the tail shank of the bracket are both provided with pivot shaft holes.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to specific embodiments: like Figures 1-4As shown, a tolerance curing fixture for a medical device includes an electrode assembly tolerance curing fixture and a jaw assembly tolerance curing fixture. The electrode assembly tolerance curing fixture is used to bond and fix a ceramic part 311 and an electrode sheet 312 to form an electrode assembly 31. The jaw assembly tolerance curing fixture is used to bond and fix the electrode assembly 31, a support 32, and a jaw fixing member 33 to form a jaw assembly 3. The ceramic part 311 and the electrode sheet 312, and the electrode assembly 31 and the support 32 are bonded with medical adhesive. The two jaw assemblies 3 are assembled to form a target part with upper and lower jaws, which is applied to a disposable high-frequency bipolar surgical electrode. After assembly with this tolerance curing fixture, the target part with upper and lower jaws can meet the requirement that the gap between the upper and lower jaws is 0.06-0.16mm after the jaws are closed, which improves the yield of the target part and reduces the repetitive input cost of the curing process.

[0021] like Figure 1 and Figure 2As shown, the electrode assembly tolerance curing fixture includes a fixing fixture 11 and a clamping assembly 12. The fixing fixture 11 includes a fixing plate 111 and a positioning member 112 for fixing the ceramic part 311 and the electrode sheet 312. The fixing plate 111 has a contoured groove 113 for accommodating the electrode assembly 31. The fixing plate 111 in which the ceramic part 311 is partially embedded is the first tolerance plate 1111, and the fixing plate 111 in which the electrode sheet 312 is partially embedded is the second tolerance plate 1112. The fixing plate 111 has a plurality of positioning holes 1113. The first and second tolerance plates 1111 and 1112 are fixed by the positioning member 112 through the positioning hole 1113, so that the ceramic part 311 and the electrode sheet 312 are relatively fixed in position during curing, reducing the dimensional difference caused by positional displacement; the clamping assembly 12 includes a clamping frame 121 and a pressing handle 122. The clamping frame 121 has a through hole 1211, and one end of the pressing handle 122 passes through the through hole 1211 and abuts against the fixing plate 111, and can maintain the pressing on the fixing plate 111 during the curing process. In at least one embodiment, the fixing plate 111 is fixed in position. The fixed plate 111 is a rectangular plate. It has two symmetrical circular positioning holes 1113. The positioning element 112 is a pin. The clamping frame 121 has a C-shaped cross-section. A pressure plate is installed at one end of the extrusion handle 122, which passes through the through hole 1211. The through hole 1211 is a circular threaded hole. The extrusion handle 122 has threads that mate with the through hole 1211. By rotating the extrusion handle 122, the pressure plate is pressed tightly onto the fixed plate 111. After fixing, the electrode assembly tolerance curing fixture containing the electrode assembly 31 is placed... The medical adhesive is cured in a constant temperature drying oven for 40-50 minutes at a temperature of 60-100 degrees Celsius. The type of medical adhesive used is E-85TP-W. During the curing process, the clamping component 12 makes the ceramic parts 311 and electrode plates 312, which have different sizes, fit more tightly and automatically fits relatively flat. This solves the problem of uneven bonding and positional misalignment caused by individual differences between the ceramic parts 311 and electrode plates 312, thereby reducing the dimensional deviation of the electrode assembly 31.

[0022] like Figures 5-10As shown, the jaw assembly tolerance fixture is used to ensure a relatively flat fit between the electrode assembly 31 and the support 32, thereby reducing dimensional differences in the jaw assembly 3. The jaw assembly tolerance fixture includes a fixture base 21, a lever assembly 22, and a tension assembly 23. The fixture base 21 is provided with a locking position 211 for placing the jaw assembly 3 and a fixture platform 212 for supporting the electrode assembly 31. When the jaw assembly 3 is placed in the locking position 211, the fixture platform 212 abuts against the bottom surface of the electrode assembly 31, and the fixture base 21 is away from the locking position 21. One end of component 1 has several fastening holes 213, and fasteners 2131 are inserted into the fastening holes 213 to fix the clamp 231 to the tooling base 21; the tension assembly 23 includes the clamp 231 and an elastic element 232, with both ends of the elastic element 232 connected to the clamp 231 and the jaw assembly 3 respectively, and the clamp 231 is installed at the end of the tooling base 21 away from the locking position 211; the lever action assembly 22 includes a conversion component 221 connecting the elastic element 232 and the jaw assembly 3, as well as a rotating shaft component 222 and a translation component 223. A conversion hole 2211 is provided at one end of the elastic element 232 near the elastic element 232. The end of the elastic element 232 away from the clamp 231 passes through the conversion hole 2211 and connects with the conversion element 221. A horizontal connecting hole 2212 is provided at the end of the conversion element 221 away from the elastic element 232. A horizontal sliding groove 2112 is provided on the side wall of the locking position 211. An oblique hole 321 is provided on the tail shank of the bracket 32. The oblique hole 321 is inclined downward from the side near the electrode assembly 31 to the side near the elastic element 232. When the electrode assembly 31 is tilted and located below the bracket 32, the inclined hole 321 tilts downward from the side near the electrode assembly 31 to the side near the tailstock of the bracket 32. The translation member 223 sequentially passes through the sliding groove 2112 on one side wall of the locking position 211, the inclined hole 321 on one side of the tailstock of the bracket 32, and the conversion hole 2211, and then passes out from the inclined hole 321 on the other side of the tailstock of the bracket 32 ​​and the sliding groove 2112 on the other side wall of the locking position 211, thereby installing the conversion member 221 on the tooling base 21 and connecting it with the jaw assembly 3.Both the side wall of the locking position 211 and the tail shank of the bracket 32 ​​are provided with pivot holes 2111. The pivot holes 2111 are located on the side of the slide groove 2112 and the oblique hole 321 near the tooling platform 212. The pivot component 222 passes through the pivot hole 2111 on one side wall of the locking position 211, the pivot hole 2111 on the bracket 32, and then exits from the pivot hole 2111 on the other side wall of the locking position 211, thereby installing the jaw assembly 3 on the tooling base 21. The conversion component 221 can extend the tail shank of the bracket 32, which facilitates the connection between the elastic component 232 and the bracket 32. Because the internal space of the tail shank of the bracket 32 ​​is very small, the conventional elastic component 232 cannot easily extend into the tail shank of the bracket 32 ​​and cannot effectively connect with the translation component 223. Next, by restricting the conversion component 221 in both the horizontal and vertical directions through the tooling base 21, the conversion component 221 effectively ensures that the translation component 223 is subjected to parallel force in the horizontal direction within the tooling base 21. After pressing down the clamp 231, the elastic component 232 drives the conversion component 221 and the translation component 223 to move towards the clamp 231. Due to the effect of the oblique hole 321, the jaw assembly 3 will move in a circular trend around the pivot component 222, thereby making the bottom surface of the electrode assembly 31 in the jaw assembly 3 tightly fit with the upper end surface of the tooling platform 212, so that the jaw assembly 3 with different dimensions can automatically fit together relatively flat. When the medical adhesive is curing, the elastic component 232 is always under force. In at least one embodiment, the number of fastening holes 213 and fasteners 2131 is four, respectively fixing the four corners of the clamp 231. The elastic element 232 is a tension spring, silicone rod, silicone strip, or other high-temperature resistant elastic material. Both ends of the elastic element 232 are hooks, which are respectively hung on the pull rod of the clamp 231 and the conversion hole 2211 of the conversion element 221. The pivot 222 and the translation element 223 are rod-shaped objects made of needle gauges, stainless steel rods, rigid iron wire, tungsten alloy rods, or other materials. The pivot hole 2111 is a circular hole, and the sliding groove 2112 and the oblique hole 321 are oblong holes. The installation position of the clamp 231 is determined by calculating the required tension of the elastic element 232 based on the force required for the clamp jaws to close during clinical use.

[0023] like Figures 5-10As shown, the locking position 211 restricts the lateral freedom of the jaw assembly 3. The rotating shaft 222 matches the rotating shaft hole 2111 of the tooling base 21 and the jaw assembly 3. After insertion, it restricts the longitudinal freedom of the jaw assembly 3, ensuring that the position of the jaw assembly 3 relative to the tooling base 21 does not shift. In the initial state, the elastic element 232 is in its natural length or slightly pre-tensioned state. When the clamp 231 is pressed down, the connection point of the clamp 231 will rotate downward around the fulcrum, causing the elastic element 232 to be stretched. At this time, the elastic element 232 is subjected to a pulling force along its own axis towards the clamp 231. The clamp 231 will be pulled by the lever. The structure amplifies the force and pulls the elastic element 232. After being stretched, the elastic element 232 generates a tensile force that tends to restore its original length. This tensile force is transmitted to the tail shank of the jaw assembly 3 through the conversion element 221. Since the jaw assembly 3 is supported by the tooling platform 212, the tensile force transmitted by the elastic element 232 makes the bottom surface of the electrode assembly 31 fit with the tooling platform 212, thereby making the electrode assembly 31 and the bracket 32 ​​fit more evenly and reducing dimensional differences. By pulling the elastic element 232 through the clamp 231, sufficient tensile force can be generated, avoiding the problem of insufficient force or uneven force when the elastic element 232 is pulled directly by hand.

S3. Place the electrode assembly tolerance curing fixture containing electrode assembly 31 into a constant temperature forced-air drying oven for curing medical adhesive. The curing time is 45 minutes and the curing temperature is 80 degrees Celsius. S4. After the medical adhesive has cured, remove the electrode assembly 31 from the electrode assembly tolerance curing fixture and assemble the bracket 32 ​​and jaw fixing piece 33 onto the electrode assembly 31 according to the normal assembly procedure.

[0025] Instructions for using the jaw assembly tolerance curing fixture: S1. Use fastener 2131 to lock the clamp 231 onto the tooling base 21, insert the jaw assembly 3 into the slot 211, insert the end of the adapter 221 with the connection hole 2212 into the tail shank of the bracket 32, connect one end of the elastic element 232 to the end of the adapter 221 with the conversion hole 2211, and connect the other end of the elastic element 232 to the clamp 231. S2. Insert the rotating shaft 222 sequentially into the rotating shaft hole 2111 on one side wall of the locking position 211, the rotating shaft hole 2111 on the bracket 32, and then out through the rotating shaft hole 2111 on the other side wall of the locking position 211, thereby installing the jaw assembly 3 on the tooling base 21. Insert the translation component 223 sequentially into the sliding groove 2112 on one side wall of the locking position 211, the oblique hole 321 on one side of the tail handle of the bracket 32, and the conversion hole 2211, and then out through the oblique hole 321 on the other side of the tail handle of the bracket 32 ​​and the sliding groove 2112 on the other side wall of the locking position 211, thereby installing the conversion component 221 on the tooling base 21 and connecting it with the jaw assembly 3. S3, Press down the clamp 231 to force the elastic element 232, and through the lever action of the rotating shaft 222, the translation element 223 and the tail handle of the bracket 32, make the jaw assembly 3 fit tightly against the tooling platform 212. S4. Place the jaw assembly 3 together with the jaw assembly tolerance fixture into a constant temperature forced-air drying oven for medical adhesive curing. The curing time is 45 minutes and the curing temperature is 80 degrees Celsius. S5. After the medical adhesive has cured, remove the jaw assembly 3 from the jaw assembly tolerance curing fixture, and assemble the two jaw assemblies 3 according to the normal assembly process to obtain the target part with upper and lower jaws.

[0026] Comparative example: like Figure 11 As shown, the assembly process of electrode assembly 31 is as follows: ceramic parts 311 and electrode sheets 312 are assembled together according to the assembly process to form electrode assembly 31. Then, these electrode assemblies 31 are placed on tooling base plate 41. In at least one embodiment, tooling base plate 41 can accommodate 12 electrode assemblies 31. A silicone pad 42 is placed on the electrode assembly 31. Then, a whole pressure plate 43 is placed on the silicone pad 42 and locked with fasteners 2131 before medical adhesive is applied for curing.

[0027] Assembly process of jaw assembly 3: The cured electrode assembly 31 is installed on the bracket 32 ​​coated with glue, and the positioning part 112 of jaw assembly 3 is installed at the end of the electrode assembly 31.

[0028] Since there are size differences between each ceramic component 311, pressing them with a single platen 43 will cause different forces on each ceramic component 311, resulting in size differences in the electrode assembly 31 after the medical adhesive has cured. During the curing process after the electrode assembly 31 is installed on the adhesive-coated bracket 32, uneven bonding surfaces may occur, further causing size differences in the jaw assembly 3, which in turn affects the pass rate of the final target parts.
