Description

Technical Field

[0001] The invention relates to the technical field of medical hemostatic instruments, and more particularly to a hemostatic device for assisting hepatobiliary and pancreatic surgery. Background Art

[0002] Hepatobiliary and pancreatic surgery is a surgical procedure used to treat diseases of organs such as the liver, gallbladder, pancreas and spleen. During clinical surgical operations, electrosurgical instruments such as electrocoagulators, argon gas knives, radiofrequency hemostatic knives, microwave knives, etc. are used to stop bleeding from incisions, or local hemostatic agents such as hemostatic powders are used, which can be sprayed or applied on the surgical wound to achieve a hemostatic effect. Since the hemostatic effect that can be achieved by using a single hemostatic method often cannot meet the intraoperative hemostasis requirements, a hepatobiliary and pancreatic postoperative wound hemostasis device such as the prior art publication number CN114587566B and a hepatobiliary surgery rapid hemostasis device such as the prior art publication number CN110960316A are used clinically to accelerate the hemostasis efficiency by combining electrocoagulation hemostasis with powder hemostasis.

[0003] It is known that the principle of electrocoagulation hemostasis is to use the thermal effect of high-frequency current to produce coagulated eschar locally in the tissue, thereby achieving rapid hemostasis. That is to say, after electrocoagulation hemostasis is performed in the prior art CN114587566B and CN110960316A, residual heat will remain on the electrode head, but in the prior art CN114587566B and CN110960316A, the electrode head and the hemostatic sponge are distributed in a cross or L shape, which results in the electrode head and the patient being relatively close when the hemostatic sponge is used for hemostasis. In this case, the electrode head with residual heat is easy to contact with other tissues in the patient's body during the operation of the hemostatic sponge head, resulting in the risk of other tissues being scalded by the residual heat of the electrode head. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a hemostatic device for assisting hepatobiliary and pancreatic surgery.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Refer to the instruction manual Figure 1 and 2 The present invention provides a hemostatic device for assisting hepatobiliary and pancreatic surgery, comprising a handle 1 and a protective shell 2 fixed at the bottom of the handle 1. The top of the handle 1 is provided with a wire 6 for connecting to an electrocoagulation host. One end of the wire 6 is also connected to a plug. When in use, the plug can be directly inserted into the socket of the electrocoagulation host. The protective shell 2 is provided with an electrocoagulator 4 for electrocoagulation hemostasis and a hemostat 5 for powder hemostasis. The electrocoagulator 4 is located on one side of the hemostat 5. The handle 1 is provided with a conversion part 7 for alternately pushing the electrocoagulator 4 and the hemostat 5 out of the bottom of the protective shell 2.

[0043] The specific structure of the conversion member 7 is as follows: Figure 4-6 As shown: it includes an air box 71 fixed inside the handle 1, and two cylindrical cavities and air holes 75 are arranged side by side inside the air box 71. The air holes 75 are located at the top of the air box 71, and the two cylindrical cavities are connected through the air holes 75. A piston rod 72 is arranged inside each cylindrical cavity, and the bottom ends of the two piston rods 72 extend from the bottom of the air box 71, respectively used to push the electrocoagulator 4 and the hemostat 5;

[0044] Moreover, the cylindrical cavity at the top of the piston rod 72 is filled with gas, and under the action of the gas, the internal air pressure of the air box 71 is greater than the atmospheric pressure. An iron rod 73 is fixed in the middle of the top of the piston rod 72, and electromagnets 74 are fixed at the top of the inner walls of the two cylindrical cavities. The on and off states of the two electromagnets 74 are opposite, and the on and off state of the electromagnets 74 is controlled by a control button B77 installed on one side of the handle 1. The outer ends of the two piston rods 72 are covered with springs 76, one end of the spring 76 is fixed to the piston head of the piston rod 72, and the other end of the spring 76 is fixed to the inner wall of the air box 71. By moving the control button B77 downward, the electromagnet 74 located directly above the electrocoagulator 4 can be energized and the electromagnet 74 located directly above the hemostat 5 can be de-energized. At this time, the on and off states of the two electromagnets 74 are the same as Figure 6 On the contrary, the compressed spring 76 located above the electrocoagulator 4 will push the piston rod 72 upward, and the energized electromagnet 74 will also attract the iron rod 73 on the top of the electromagnet 74 until the piston rod 72 above the electrocoagulator 4 moves to the top of the cylindrical cavity, and the piston rod 72 can also be fixed in this position due to the adsorption effect between the electromagnet 74 and the iron rod 73; at the same time, the other piston rod 72 will move downward under the action of the spring 76 stretched at its outer end, and the upward piston rod 72 will also squeeze the gas at its top to pass through the air vent 75 and move into the cylindrical cavity next door, and the gas can further push the piston rod 72 downward, promote the change of the positions of the two piston rods 72, thereby driving the electrocoagulator 4 and the hemostat 5 at the bottom of the piston rod 72 to move up and down synchronously, thereby realizing the switching of the positions of the electrocoagulator 4 and the hemostat 5;

[0045] like Figure 6 As shown: the electrocoagulator 4 includes a coagulator handle 41, and the bottom end of the electrocoagulator handle 41 is detachably connected to an electrode 42. This arrangement enables the electrode 42 to be replaced according to actual operating needs, so that the present invention can be applied to different operating environments. When performing electrocoagulation hemostasis, the doctor can control the electrode 42 through one of the control buttons A8 installed on the outer wall of the protective shell 2. When the control button A8 is pressed, the electrode 42 is energized and generates high temperature. At this time, the bleeding tissue can be electrocoagulated. After the electrocoagulation is completed, the control button A8 is released, and then the electrode 42 is powered off. The doctor's operation is relatively simple.

[0046] In addition, a mounting seat 43 is installed at the top of the electrocoagulator handle 41, and the electrocoagulator handle 41 can be fixed to the bottom end of one of the piston rods 72 through the mounting seat 43. In this way, the piston rod 72 can be used to draw the electrode 42 with residual heat back into the protective shell 2 after the electrode 42 works. On the one hand, it can prevent the residual heat of the electrode 42 from scalding the surrounding tissues, and on the other hand, it can also clear the operating field of the protective shell 2, making it convenient for the doctor to observe the hemostasis position and achieve precise hemostasis.

[0047] It is worth noting that the protective shell 2 in the present invention is made of heat-insulating material, which can prevent the protective shell 2 from absorbing the residual heat of the electrode 42 and scalding the doctor, thereby improving the safety of the present invention when in use. A protective cap 3 is also threadedly connected to the bottom end of the protective shell 2. When not in use, the protective cap 3 can be directly installed on the bottom end of the protective shell 2, so that the protective cap 3 can cover the outer end of the electrocoagulator 4 or the hemostat 5 extending from the bottom end of the protective shell 2, thereby protecting the electrocoagulator 4 and the hemostat 5.

[0048] When using hemostatic powder to stop bleeding, the hemostat 5 needs to be extended from the inside of the protective shell 2 and the electrocoagulator 4 needs to be retracted into the inside of the protective shell 2. To achieve this effect, the doctor can control the control button B77 to move down with one hand to switch the positions of the electrocoagulator 4 and the hemostat 5, so that the hemostat 5 can be adjusted to the position as shown in the figure. Figure 3 Position shown.

[0049] Furthermore, if Figure 5-9 As shown, the specific structure of the hemostat 5 includes a hollow rod 515 installed inside the protective shell 2, the top of the hollow rod 515 is connected to the bottom of the piston rod 72, so that the piston rod 72 can drive it to move up and down, and a medicine storage ball 54 is inlaid at the bottom of the hollow rod 515, and the bottom end of the medicine storage ball 54 is threadedly connected to a connecting tube 53, and the bottom end of the connecting tube 53 is fixed with an upper medicine ball 52, and the outer end of the upper medicine ball 52 is covered with a sponge cover 51, and the outer walls of the upper medicine ball 52 and the outer walls of the sponge cover 51 are provided with through holes for removing medicine powder, and the sponge cover 51 can be made of medical gelatin sponge, which is an absorbable porous substance that can absorb liquid more than 30 times its own volume, and can play a compressive hemostasis effect under the action of local gravity, and can absorb a large amount of blood, which is beneficial to the exposure of the surgical field. It contains positron attachments, which are conducive to the adsorption of platelets and the formation of small thrombi locally, thereby playing a hemostatic role and activating endogenous and exogenous hemostatic pathways. At the same time, the hemostatic powder inside the medicine storage ball 54 can also be moved out through the through holes on the sponge sleeve 51 to contact the bleeding site, thereby further enhancing the hemostatic effect of the present invention.

[0050] Since the blood may block the through hole on the sponge cover 51 after contacting the hemostatic powder, when the hemostat 5 is used to stop bleeding, the sponge cover 51 can be kept vertically downward to allow the hemostatic powder to move out through the through hole at the bottom of the sponge cover 51. When the through hole at the bottom of the sponge cover 51 is blocked, the sponge cover 51 is rotated to allow the hemostatic powder to leak out from other positions of the sponge cover 51 to continue to stop bleeding. To achieve this effect, Figure 7-9As shown, the present invention has a connecting column 56 fixed in the middle of the top of the medicine storage ball 54, and the top of the connecting column 56 is connected to a pull rope 57. A rotating platform 59 is provided at the top of the medicine storage ball 54. A limit ring 514 is fixed on the outer wall of the rotating platform 59. The limit ring 514 is embedded in the inner wall of the hollow rod 515. The top of the pull rope 57 passes through the rotating platform 59 and is fixedly connected to a rotating rod 510. A rod frame 511 for mounting the rotating rod 510 is fixed on the top of the rotating platform 59. The rotating rod 510 is movably connected to the rod frame 511 through a bearing. 510 is driven by a motor that can rotate forward and backward. The rotating rod 510 is rotated to reel in the pull rope 57 to pull the medicine storage ball 54. A guide rod 58 is fixed to one side of the bottom end of the rotating platform 59. The pull rope 57 passes around the outer wall of the guide rod 58 to limit the direction of the pull rope 57 to achieve the effect of pulling the medicine storage ball 54 to one side. After the medicine storage ball 54 is pulled, it will rotate at the bottom end of the hollow rod 515, so that the sponge cover 51 and the upper medicine ball 52 installed at the bottom end of the medicine storage ball 54 are tilted to one side, so that the hemostatic powder can be easily removed from other positions.

[0051] In order to change the removal position of the hemostatic powder again, the present invention also fixes a ring gear 512 on the top of the inner wall of the rotating table 59, and a gear 513 is meshed inside the ring gear 512. The gear 513 is driven by a motor, and the rotating gear 513 drives the ring gear 512 to drive the rotating table 59 to rotate, thereby driving the medicine storage ball 54 to circle horizontally at the bottom end of the hollow rod 515, so that the upper medicine ball 52 and the connecting tube 53 can be tilted in different directions at the bottom end of the protective shell 2, so that the hemostatic powder can leak out from different positions of the sponge sleeve 51.

[0052] The doctor can adjust the angle of the sponge cover 51 through the control button A8 fixed on the outer wall of the protective shell 2. After pressing one of the control buttons A8, the sponge cover 51 starts to rotate immediately. After releasing the control button A8, the sponge cover 51 stops rotating. The doctor can stop and use it at any time, and it can be completed with one hand, which reduces the difficulty of operation for the doctor.

[0053] In the above process, the start control of the motor driving the rotating rod 510 and the motor driving the gear 513 are both realized by the control button A8 installed at the outer end of the protective shell 2. By long pressing one of the control buttons A8, the motor at one end of the rotating rod 510 is controlled to start, and by long pressing the other control button A8, the motor driving the gear 513 is controlled to start. When the hand is released, the motor stops working immediately.

[0054] In addition, it is worth mentioning that the upper medicine ball 52 and the medicine storage ball 54 in the present invention are detachable. The sponge cover 51 is a disposable consumable, and the upper medicine ball 52 can be removed and reused after cleaning and disinfection. At the same time, the detachable design can also make it convenient for medical staff to add hemostatic powder to the medicine storage ball 54. After the upper medicine ball 52 is removed from the bottom of the medicine storage ball 54, the medical staff can add the powder to the medicine storage ball 54 from the bottom of the medicine storage ball 54. In order to prevent the powder in the medicine storage ball 54 from leaking out of the through hole of the upper medicine ball 52 when not in use, Figure 7 and Fig. 9 As shown, a medicine discharging control valve 55 for preventing medicine powder from passing through is fixed on the outer wall of the bottom end of the medicine storage ball 54, and the medicine discharging control valve 55 includes a valve plate 551 arranged above the outlet of the bottom end of the medicine storage ball 54, and rotating shafts 552 are fixed at both ends of the valve plate 551, and the rotating shaft 552 is movably connected to the outer wall of the bottom end of the medicine storage ball 54 through bearings, and a gear rack transmission mechanism 553 for driving the valve plate 551 to flip 90° is provided on the outer end of one of the rotating shafts 552, and a fixed cover 554 is fixed on the outer wall of the bottom end of the medicine storage ball 54, and the gear rack transmission mechanism 553 is installed inside the fixed cover 554, and the gear rack transmission mechanism 553 is driven by a reciprocating screw assembly driven by a motor, and the distance that the rack in the gear rack transmission mechanism 553 moves is equal to one-fourth of the circumference of the gear dividing circle in the gear rack transmission mechanism 553. This design will make the rack only drive the gear to rotate 90° each time it moves, so that Fig. 9 The valve plate 551 in the horizontal state shown in the figure is turned to a vertical state, and only when the valve plate 551 is in a vertical state can the medicine powder pass through the bottom of the medicine storage ball 54 and enter the interior of the upper medicine ball 52. Fig. 9 The state shown can prevent the medicine powder from leaking out through the upper medicine ball 52. The drive control of the gear rack transmission mechanism 553 is also realized by the control button A8 installed at the outer end of the protective shell 2. When the doctor presses one of the control buttons A8, the gear rack transmission mechanism 553 drives the valve plate 551 to flip 90°.

[0055] In addition, in order to conveniently display the state of the valve plate 551, a red and green indicator light may be installed on the outer wall of the protective shell 2, and the green indicator light is on when the valve plate 551 is in a horizontal position, and the red indicator light is on when the valve plate 551 is in a vertical position. Using lights of different colors to display the state of an object is a common technical means in the prior art, which can be easily achieved by existing technical means, and therefore will not be further described in the present invention.

[0056] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
