Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a pair of brain tumor removal forceps which can avoid tumor rupture. Background Art

[0002] Brain tumors are also called intracranial tumors, or "brain tumors", and are the most common diseases in neurosurgery. Most are primary intracranial tumors that originate from various tissues within the skull. Secondary intracranial tumors originate from the metastasis of malignant tumors in other parts of the body or the invasion of tumors in adjacent tissues. Brain tumors are divided into benign brain tumors and malignant brain tumors. Currently, medical treatment for brain tumors usually adopts a treatment plan of surgical resection and then removal with clamps. When removing brain tumors, brain tumor removal forceps are usually used to assist in removing brain tumors.

[0003] For example, the public document with application number 2019 20619701.1 discloses a brain tumor removal forceps. The utility model achieves the effect of increasing the friction between the doctor's fingers and the handle through the cooperation of the anti-slip ring and the handle, thereby preventing the doctor's fingers from losing contact with the handle during the process of clamping the tumor mass, making it easier for the doctor to use the removal forceps to clamp the tumor mass more stably. However, when the brain tumor removal forceps are used to remove the tumor, the clamping force is difficult to control, which may cause the tumor to rupture during the clamping process, affecting the tumor removal work.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a brain tumor removal forceps that can avoid tumor rupture is proposed. Utility Model Content

[0005] The utility model aims to provide a brain tumor removal forceps which can avoid tumor rupture, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a brain tumor removal forceps that can avoid tumor rupture, including a forceps body, the forceps body is divided into two parts, and a guide groove is opened on the opposite side of the surface of the forceps body, and a fixed cylinder is installed on the left end of the opposite side of the surface of the forceps body, and a thrust spring is fixedly arranged on the inner surface of the fixed cylinder, and a movable column is fixedly arranged on the end of the thrust spring close to the opening of the fixed cylinder, and the connecting end of the movable column and the thrust spring is slidably fitted on the inner surface of the fixed cylinder, and a suction cup is fixedly installed on the opposite end of the movable column.

[0007] Preferably, an insert block is fixedly mounted on the right end of the pliers body, and a screw hole is penetrated through the middle of the surface of the insert block.

[0008] Preferably, the rear sides of the caliper bodies are respectively provided with a first mounting foot and a second mounting foot, and the rear side of the upper caliper body corresponds to the second mounting foot, and the rear side of the lower caliper body corresponds to the first mounting foot.

[0009] Preferably, the front ends of the first mounting foot and the second mounting foot are both provided with insertion holes, and the front ends of the first mounting foot and the second mounting foot on opposite sides of the surface are both provided with thread grooves, and the thread grooves are connected to the insertion holes.

[0010] Preferably, a fixing bolt is threadedly connected to the inner surface of the thread groove, and a protrusion is fixedly provided at the end of the fixing bolt.

[0011] Preferably, a fixing plate is fixedly mounted on the rear end of the first mounting foot, an arc groove is provided above the surface of the fixing plate, and an assembly ring is rotatably provided on the middle part of the front side of the surface of the fixing plate through a bearing.

[0012] Preferably, a connecting block is obliquely arranged above the left end of the surface of the assembly ring, and the connecting block is slidably arranged inside the arc groove, and the connecting block is fixedly connected to the right end of the second mounting foot.

[0013] Preferably, an extension plate is fixedly provided on the right ends of the surfaces of the fixing plate and the assembly ring, and a pinching ring is fixedly provided on the opposite side of the right end of the surface of the extension plate.

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

[0015] 1. The utility model drains dirty blood through the arrangement of the guide groove, the fixed cylinder, the thrust spring, the movable column and the suction cup, and the sinking of the guide groove prevents the dirty blood from overflowing on the surface of the clamp body and contaminating the entire device when clamping the tumor. When clamping the tumor, the suction cup contacts the tumor first, and the suction cup is in a concave state, covering both sides of the tumor, making the clamping more stable, and increasing the clamping surface, so that the clamping force can be evenly dispersed, avoiding the tumor from being ruptured due to a single force point during clamping. The elastic contraction and extension ability of the thrust spring itself can drive the movable column to contract into the fixed cylinder, and can reduce the clamping force applied manually to a certain extent, avoiding the situation where a single clamping force is too large and causing the tumor to rupture. At the same time, after the thrust spring contracts and releases the force, it uses its own elastic thrust to always maintain the clamping force on the movable column and the suction cup in the opposite direction, so that medical staff can use a smaller clamping force, achieve effective clamping stability, and make the overall use of the device safer, more stable, and more labor-saving;

[0016] 2. The utility model is provided with an insert block, a screw hole, a first mounting foot, a second mounting foot, an insert hole, a threaded groove, a fixing bolt and a protrusion. The insert block is inserted into the insert hole, and then the fixing bolt is screwed into the threaded groove and the screw hole to install the pliers body. The pliers body and the gripping part can be disassembled by screwing out the fixing bolt, and the pliers body can be separately packaged and stored. After disassembly, it is also convenient to disinfect and clean the pliers body separately. The overall device only needs to replace the pliers body, which can save a certain cost. The fixing bolt can be directly screwed through the protrusion without the help of other tools, which is more convenient and simple when disassembling and assembling;

[0017] 3. The utility model provides a fixing plate, an arc groove, an assembly ring, a connecting block, an extension plate and a pinching ring. An artificial finger is inserted into the pinching ring to prevent the clamp from falling off during the clamping process, making the use more stable. The finger pushes the assembly ring to rotate through the extension plate, and at the same time drives the connecting block to slide along the arc groove, thereby driving the second mounting foot and the upper clamp body to rotate and open, and vice versa. The transmission can be effectively performed to complete the opening and closing clamping and taking operations. The oblique setting of the connecting block can make up for the rotation angle difference between the two straight clamp bodies, so that when closed, the opposite side of the clamp body can fit perfectly without leaving any gap, and any small tumor can be effectively clamped.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 3 As shown, a brain tumor removal forceps that can avoid tumor rupture includes a forceps body 1, which is divided into two parts, an upper part and an lower part, and a guide groove 2 is opened on the opposite side of the surface of the forceps body 1, a fixed cylinder 3 is installed on the left end of the opposite side of the surface of the forceps body 1, a thrust spring 4 is fixedly installed on the inner surface of the fixed cylinder 3, a movable column 5 is fixedly installed on the end of the thrust spring 4 close to the opening of the fixed cylinder 3, and the connecting end of the movable column 5 and the thrust spring 4 is slidably fitted on the inner surface of the fixed cylinder 3, and a suction cup 6 is fixedly installed on the opposite end of the movable column 5.

[0025] Furthermore, the sinking of the guide groove 2 drains the dirty blood, thereby preventing the dirty blood from overflowing on the surface of the clamp body 1 and contaminating the entire device when clamping a tumor.

[0026] Furthermore, the suction cup 6 contacts the tumor preferentially, and the suction cup 6 is in a concave state, covering both sides of the tumor, making the clamping more stable, and increasing the clamping surface so that the clamping force can be evenly dispersed, avoiding a single force point on the tumor during clamping and causing rupture.

[0027] Furthermore, the elastic contraction and extension capabilities of the thrust spring 4 itself can drive the movable column 5 to contract into the fixed tube 3, which can alleviate the manually applied clamping force to a certain extent, thereby avoiding the situation where a single clamping force is too large and causes tumor rupture.

[0028] Furthermore, after the thrust spring 4 contracts and releases its force, it always maintains the outward clamping force on the movable column 5 and the suction cup 6 by utilizing its own elastic thrust, so that the medical staff can use a smaller clamping force to achieve effective clamping stability.

[0029] like Figure 3-Figure 4 As shown, an insert block 7 is fixedly installed on the right end of the caliper body 1, and a screw hole 8 is opened through the middle of the surface of the insert block 7, and a first mounting foot 9 and a second mounting foot 10 are respectively provided on the rear side of the caliper body 1, and the rear side of the upper caliper body 1 corresponds to the second mounting foot 10, and the rear side of the lower caliper body 1 corresponds to the first mounting foot 9, and the front ends of the first mounting foot 9 and the second mounting foot 10 are provided with an insert hole 11, and the front ends of the first mounting foot 9 and the second mounting foot 10 on the opposite side of the surface are provided with a threaded groove 12, and the threaded groove 12 is connected to the insert hole 11, the inner surface of the threaded groove 12 is threadedly connected with a fixing bolt 13, and a protrusion 14 is fixedly provided at the end of the fixing bolt 13.

[0030] Furthermore, the insert block 7 is inserted into the insert hole 11 and can be fixed by using the fixing bolts 13 , the thread grooves 12 and the screw holes 8 , so that the caliper body 1 is installed.

[0031] Furthermore, the clamp body 1 and the gripping part can be disassembled by unscrewing the fixing bolt 13, and then separately packed and stored. After disassembly, it is also convenient to disinfect and clean the clamp body 1 separately. The whole device only needs to replace the clamp body 1, which can save certain costs.

[0032] Furthermore, the fixing bolt 13 can be directly screwed by utilizing the protrusion 14 without the aid of other tools, making disassembly and assembly more convenient and simple.

[0033] like Figure 1 and Figure 3 As shown, a fixing plate 15 is fixedly installed at the rear end of the first mounting foot 9, and an arc groove 16 is opened above the surface of the fixing plate 15, and an assembly ring 17 is rotatably arranged on the front middle part of the surface of the fixing plate 15 through a bearing, a connecting block 18 is obliquely arranged above the left end of the surface of the assembly ring 17, and the connecting block 18 is slidably arranged inside the arc groove 16, and the connecting block 18 is fixedly connected to the right end of the second mounting foot 10, and an extension plate 19 is fixedly arranged on the right ends of the surfaces of the fixing plate 15 and the assembly ring 17, and a pinching ring 20 is fixedly arranged on the opposite side of the right end of the surface of the extension plate 19.

[0034] Furthermore, the artificial fingers are inserted into the pinch ring 20 to prevent the fingers from falling off during the clamping process, making the use more stable.

[0035] Furthermore, the fingers push the assembly ring 17 to rotate through the extension plate 19, and at the same time drive the connecting block 18 to slide along the arc groove 16, thereby driving the second mounting foot 10 and the upper clamp body 1 to rotate and open, and vice versa, to close, which can effectively transmit and complete the operation of opening and closing the clamp.

[0036] Furthermore, the oblique setting of the connecting block 18 makes up for the rotation angle difference between the two straight clamp bodies 1, so that when closed, the opposite sides of the clamp bodies 1 can fit perfectly without leaving any gap, and any small tumor can be effectively clamped.

[0037] Working principle: When using the brain tumor removal forceps that can prevent tumor rupture, first, insert the plug block 7 into the socket 11, and then screw the fixing bolt 13 into the threaded groove 12 and the screw hole 8 to install the forceps body 1. After the forceps body 1 is installed, insert the pinch ring 20 with an artificial finger, and push the assembly ring 17 to rotate through the extension plate 19, while driving the connecting block 18 to slide along the arc groove 16 and then drive the second installation foot 10 and the upper side forceps body 1 to rotate and open, otherwise close, and perform the clamping work. When clamping the tumor, the suction cup 6 contacts the tumor first, and the suction cup 6 is in a concave state, covering both sides of the tumor, and draining the dirty blood through the sinking of the guide groove 2. During the clamping process, the thrust The elastic contraction and extension ability of the spring 4 itself can drive the movable column 5 to contract into the fixed tube 3, and can reduce the manually applied clamping force to a certain extent, avoiding the situation where a single clamping force is too large and causes tumor rupture. At the same time, after the thrust spring 4 contracts and releases the force, it uses its own elastic thrust to always maintain the opposite outward clamping force on the movable column 5 and the suction cup 6, so that medical staff can use a smaller clamping force to achieve effective clamping stability. After the tumor is removed, the pliers body 1 and the holding part can be disassembled by pinching the protrusion 14 and rotating it, and unscrewing the fixing bolt 13, and the pliers body 1 can be packaged and stored. After disassembly, it is also convenient to disinfect and clean the pliers body 1 separately. This is the working principle of the brain tumor removal forceps that can avoid tumor rupture.
