Description

Technical Field

[0001] The invention belongs to the technical field of medical appliances, in particular to a myocardectomy device. Background Art

[0002] Cardiac muscle is a muscle tissue composed of myocardial cells. In a broad sense, myocardial cells include special differentiated myocardial cells that make up the sinoatrial node, intraatrial bundle, atrioventricular junction, atrioventricular bundle (i.e. His bundle) and Purkinje fibers, as well as general atrial and ventricular working cells. The first five types constitute the cardiac pacemaker conduction system. They contain very few or no myofibrils, so they have no contractile function; however, they have autonomy and conductivity, which is the functional basis of cardiac autonomic activity; the latter two types have contractility, which is the functional basis of cardiac systolic and diastolic activity. Hypertrophic cardiomyopathy (Hypertrophic myocardium) Hypertrophic cardiomyopathy (HCM) is a type of heart disease characterized by left ventricular hypertrophy, asymmetric thickening of the ventricular septum, smaller ventricular cavity, restricted ventricular filling during diastole and obstruction of the left ventricular outflow tract. This disease often has a family history. About 50% of patients have genetic abnormalities, mostly familial autosomal dominant inheritance. Clinically, there is a decrease in cardiac output, causing palpitations, angina pectoris, and dyspnea due to pulmonary hypertension. Some patients experience transient syncope or even sudden death. Hypertrophic cardiomyopathy (HCM) causes abnormal thickening of the myocardium, which may cause cardiac dysfunction and arrhythmia. Resection of part of the myocardium can improve the heart's pumping function.

[0003] Patients with hypertrophic cardiomyopathy need to have a portion of the myocardium removed to ensure their health, and undergo myocardectomy. During myocardectomy, the chest cavity is entered through sternotomy or other methods to remove the myocardium. However, after the chest cavity is removed, the patient's chest cavity is still in a closed state, and an external clamp is needed to clamp the patient's chest cavity open to facilitate personnel to observe the situation inside the chest cavity.

[0022] In this embodiment, when performing a myocardial resection, it is necessary to enter the chest cavity through a sternotomy. By expanding the chest cavity, a better surgical field of view can be obtained, which is convenient for surgeons to observe and operate the heart and surrounding structures. Expanding the chest cavity can reduce pressure on the heart and large blood vessels, thereby reducing the risk of tissue damage during the operation. By using an adsorption-type expansion component, the firmness of the clamping and expansion can be improved, avoiding the chest cavity from loosening due to insufficient clamping during the myocardial resection, resulting in the chest cavity closing again, affecting the operation and easily causing medical accidents.

[0023] Embodiment 2: Figures 1 to 8 As shown in Comparative Example 1, another embodiment of the present invention is: The blood cleaning component includes a magnetic sheet A 4, the outer surface of which is fixedly connected to the inside of the groove B, a magnetic sheet B 5 is magnetically attracted to one side of the magnetic sheet A 4, a suction head 6 is fixedly connected to one side of the magnetic sheet B 5, a blood cleaning hole is opened on the surface of the suction head 6, a telescopic hose 7 is fixedly connected to the edge of the blood cleaning hole, a connecting tube 8 is fixedly connected to one end of the telescopic hose 7, and a storage disk 9 is fixedly connected to one end of the connecting tube 8. When performing a myocardial resection operation, it is necessary to enter the chest cavity through a sternotomy. During the resection, it is necessary to focus on controlling the thickness of the resection to avoid errors in the resection thickness and harm to the patient. However, when the chest cavity is cut, bleeding will occur in the chest cavity. In order to avoid blood blocking the medical staff's line of sight and causing errors in the thickness of the myocardial resection by the medical staff, the blood needs to be cleared. The blood cleaning component can quickly draw blood, and clearing the blood in the surgical area can improve the medical staff's field of vision, making it easier for them to observe the details of tissues and organs, thereby reducing surgical risks. Blood cleaning can reduce the risk of intraoperative bleeding and the possibility of hematoma formation, thereby reducing the incidence of postoperative complications.

[0024] The pumping assembly includes a micro pumping pump 10, the input end of the micro pumping pump 10 is fixedly connected to a blood drawing blood vessel 11, one end of the blood drawing blood vessel 11 is fixedly connected to one end of a storage disk 9, the output end of the micro pumping pump 10 is fixedly connected to an outlet blood vessel 12, one end of the outlet blood vessel 12 is fixedly connected to a storage tank 13, one end of the storage tank 13 is fixedly connected to a liquid outlet pipe 14, the micro pumping pump 10 drives the blood drawing blood vessel 11 and the storage disk 9 to pump, the storage disk 9 drives the connecting pipe 8 to pump, the connecting pipe 8 drives the telescopic hose 7 to pump, and then the adsorption head 6 is used to pump and adsorb the blood, and the blood is pumped into the outlet blood vessel 12, and flows from the outlet blood vessel 12 to the storage tank 13. When the blood fills the storage tank 13, it flows out from the liquid outlet pipe 14, and the blood can be collected while quickly clearing the blood to avoid contamination.

[0025] The measuring assembly includes a main measuring plate 15, one end of which is rotatably connected to the inner wall of groove A through a rotating rod 2, an auxiliary measuring plate 16 is inserted into the interior of the main measuring plate 15, and a protrusion is fixedly connected to one end of the auxiliary measuring plate 16. The surfaces of the main measuring plate 15 and the auxiliary measuring plate 16 are both provided with scale grooves. Before myocardial resection surgery, a detailed surgical plan needs to be made for the patient to reduce the surgical risk. The measuring assembly can accurately and carefully measure the position. Measuring the position helps medical staff to formulate a detailed surgical plan, including the incision position, resection range and surgical steps, thereby improving the safety and effectiveness of the surgery.

[0026] The cutting assembly includes a battery shell 17, the outer surface of the battery shell 17 is fixedly connected to the inner wall of the protective shell 3, the battery shell 17 is clamped with a battery 18, one end of the battery shell 17 is provided with a round hole, the inside of the round hole is plugged with a connecting wire, one end of the connecting wire is fixedly connected to a C magnetic sheet 19, one end of the C magnetic sheet 19 is fixedly connected to a damping rod 20, the outer surface of the damping rod 20 is sleeved with a spring 21, the A button 33 is pressed, and when the A button 33 is activated, the battery 18 is energized, and the battery 18 energizes the C magnetic sheet 19 through the connecting wire, and the C magnetic sheet 19 and the D magnetic sheet 22 are connected. The magnetic repulsion can push the D magnetic sheet 22 outward. When the D magnetic sheet 22 moves outward, it drives the connecting rod 23 and the cutting blade 24 outward, and pushes the cutting blade 24 out of the protective shell 3. The myocardium is removed by the cutting blade 24. During the removal, in order to avoid the spring 21 from shaking, the damping rod 20 can be used to increase the pressure to achieve a buffering effect and increase stability. The spring 21 can be moved slowly. When the myocardium is removed, the magnetism of the C magnetic sheet 19 resists the D magnetic sheet 22. The stability of the D magnetic sheet 22 is strong, and the cutting blade 24 will not shake during operation.

[0027] One end of the spring 21 is fixedly connected to a D magnetic sheet 22 , one end of the D magnetic sheet 22 is fixedly connected to a connecting rod 23 , and one end of the connecting rod 23 is fixedly connected to a cutting blade 24 .

[0028] A B tension rope 32 is fixedly connected to the back of the B clamping plate 29, one end of the B tension rope 32 is fixedly connected to a connecting piece 41, both ends of the connecting piece 41 are fixedly connected to clamping plates 42, both sides of the clamping plate 42 are provided with threaded holes for threadedly connecting fixing bolts 43, and the outer surface of the fixing bolts 43 is threadedly connected with nuts 44. After the chest cavity is cut open by the resection blade 24, the A clamping plate 27 and the B clamping plate 29 are attached to the outside of the chest cavity, and the micro-electric push rod 28 is started. The micro-electric push rod 28 drives the A clamping plate 27 to clamp inwards and fit the suction cup 31 to the chest cavity. Subsequently, the micro-vacuum pump 30 is started. The micro-vacuum pump 30 performs vacuum adsorption on the chest cavity adsorption part from the suction cup 31, which can enhance the expansion firmness. Subsequently, the B tension rope 32 is pulled to clamp the clamping plate 42 on the railing of the operating bed, driving the B tension rope 32 to expand the chest cavity. Subsequently, the clamping plate 42 is fixed by the fixing bolt 43 and the nut 44.

[0029] An A hole groove for fixing an A button 33 is provided on one side of the outer surface of the shell 1, and a B hole groove for fixing a B button 34 is provided on one side of the outer surface of the shell 1 close to the A button 33. The A button 33 is used to control the cutting component, and the B button 34 is used to control the pulling component.

[0030] The support assembly includes a sleeve rod 35, and a support rod 36 is inserted into the interior of the sleeve rod 35. One end of the sleeve rod 35 and the support rod 36 are provided with an A adjustment block 37. When the main measuring plate 15 is pulled vertically, the slider 40 slides in the slide groove. Subsequently, the main measuring plate 15 and the auxiliary measuring plate 16 are rotated by the A adjustment block 37 and the B adjustment block 39. When adjusting the angle, the sleeve rod 35 and the support rod 36 are used to support the main measuring plate 15, so that the inclined angle can be achieved and the main measuring plate 15 can be supported.

[0031] One side of the A adjustment block 37 is rotatably connected to the B adjustment block 39 through the rotating block 38. One end of the B adjustment block 39 is fixedly connected to the slider 40. A sliding groove is provided on the surface of the A groove. The inside of the sliding groove is slidably connected to the outer surface of the slider 40. The sliding of the slider 40 can open and store the sleeve rod 35 and the support rod 36.

[0032] like Figures 1 to 8 As shown, Working principle: Before the operation, it is necessary to make a detailed plan for the position of the incision to accurately find the incision, place one end of the shell 1 close to the patient's chest, and move the protrusion to open the auxiliary measuring plate 16 and the main measuring plate 15 to a vertical state. When the main measuring plate 15 is pulled vertically, the slider 40 slides in the slide groove. Then, the main measuring plate 15 and the auxiliary measuring plate 16 are rotated by the A adjustment block 37 and the B adjustment block 39. When adjusting the angle, the main measuring plate 15 is supported by the sleeve rod 35 and the support rod 36 to achieve an inclined angle. The main measuring plate 15 is supported to facilitate measurement. Then, when the main measuring plate 15 needs to be retracted, it is pulled downward, the slider 40 slides in the slide groove, the support rod 36 is retracted in the sleeve rod 35, and the sleeve rod 35 is stored in the groove on the surface of the shell 1. Subsequently, the auxiliary measuring plate 16 is pulled out, and the distance size is viewed by using the scale grooves on the main measuring plate 15 and the auxiliary measuring plate 16, so as to facilitate the measurement of the distance in the up, down, left and right directions of the fixed point. The measured position helps the medical staff to formulate a detailed surgical plan, including the incision position, the resection range and the surgical steps, so as to improve the safety and effectiveness of the operation. Subsequently, the A button 33 is pressed. When the A button 33 is activated, the battery 18 is energized, and the battery 18 energizes the C magnetic sheet 19 through the connecting wire. The magnetic repulsion between the C magnetic sheet 19 and the D magnetic sheet 22 can push the D magnetic sheet 22 outward. When the D magnetic sheet 22 is outward, it drives the connecting rod 23 and the cutting blade 24 outward, pushes the cutting blade 24 out of the protective shell 3, and uses the cutting blade 24 to cut the myocardium. During the cutting, in order to avoid the spring 2 1 shakes, the damping rod 20 can increase the pressure to achieve a buffering effect, increase stability, and slowly move the spring 21. When the myocardium is removed, the magnetism of the C magnetic sheet 19 resists the D magnetic sheet 22. The stability of the D magnetic sheet 22 is strong, and the cutting blade 24 will not shake when working. Then, after the chest cavity is cut open by the cutting blade 24, the A clamping plate 27 and the B clamping plate 29 are attached to the outside of the chest cavity, and the micro-electric push rod 28 is started. The micro-electric push rod 28 drives the A clamping plate 27 to clamp inwards and attach the suction cup 31 to the chest cavity. Then, the micro-vacuum pump 30 is started. The micro-vacuum pump 30 performs vacuum adsorption on the chest cavity adsorption part from the suction cup 31, which can enhance the expansion firmness. Then, the B tension rope 32 is pulled to clamp the clamping plate 42 It is connected to the railing of the operating table to drive the B tension rope 32 to expand the chest cavity. Subsequently, the clamping piece 42 is fixed by the fixing bolt 43 and the nut 44 to fix the chest cavity. The fixed chest cavity can provide a stable operating environment, allowing medical staff to operate better and reduce the surgical risks caused by chest movement. It can avoid chest obstruction during surgery and affect myocardial resection. Subsequently, when performing myocardial resection, it is necessary to focus on controlling the thickness of the resection to avoid errors in the thickness of the resection and cause harm to the patient. After the chest cavity is opened, bleeding will occur in the chest cavity. In order to avoid blood blocking the medical staff's line of sight and causing errors in the thickness of the myocardial resection, the blood needs to be cleared. Press the B button 34, and the B button 34 will start the micro pump 10 and pull the adsorption head 6 outward.The adsorption head 6 separates the B magnetic sheet 5 and the A magnetic sheet 4. After the adsorption head 6 is pulled outward, the telescopic hose 7 is pulled out. The adsorption head 6 is attached to the place where bleeding occurs. The micro pumping pump 10 drives the blood drawing tube 11 and the storage disk 9 to pump. The storage disk 9 drives the connecting tube 8 to pump. The connecting tube 8 drives the telescopic hose 7 to pump. The adsorption head 6 is then used to pump and adsorb the blood. The blood is pumped into the blood outlet blood vessel 12, and flows from the blood outlet blood vessel 12 to the storage tank 13. When the blood is full in the storage tank 13, it flows out from the liquid outlet tube 14. While quickly clearing the blood, the blood can be collected. Avoid contamination. Removing blood from the surgical area can improve the medical staff's field of vision, making it easier to observe the details of tissues and organs, thereby reducing surgical risks. Blood cleaning can reduce the risk of intraoperative bleeding and the possibility of hematoma formation, thereby reducing the incidence of postoperative complications. After the blood is removed, the myocardium is removed using the resection blade 24. Pressing the A button 33 again can cut off the power of the battery 18, release the repulsive force between the C magnetic sheet 19 and the D magnetic sheet 22, and the resection blade 24 can rebound into the protective shell 3 for storage to avoid accidental injury to medical staff.
