[0033] Breast minimally invasive rotary resection refers to resection or pathological examination of the tumor in the breast under the guidance of B-ultrasound. After breast minimally invasive rotary resection, direct hemostasis cannot be achieved, and only local compression hemostasis can be achieved, specifically, compression hemostasis is required, and bathing cannot be performed 2-3 days after compression hemostasis. Many patients are repelled, and the bulky dressing affects free movement. Therefore, the existing hemostasis mode has the problem of long hemostasis process time.
[0034] The utility model provides a hemostasis device.
[0035] Please refer to Figure 1 In an embodiment of the utility model, the hemostasis device 100 includes a contact piece 1, a negative pressure generating device 2 and a power supply assembly 3, the contact piece 1 has an attracting channel 11 penetrating along the axial direction, and the contact piece 1 is used to contact the wound, the negative pressure generating device 2 is communicated with the attracting channel 11, and the power supply assembly 3 is used to connect the external power supply to conduct electricity to the contact piece 1.
[0036] The technical scheme of the utility model contacts the contact piece 1 with the human body wound, sucks out the blood in the wound by the negative pressure generating device 2, ensures the cleanness of the wound, and then imports the high-frequency current into the contact piece 1 by the power supply assembly 3, so that the local tissue contacting the contact piece 1 is heated, when the temperature rises to a certain degree, the cell protein of the tissue is denatured and coagulated, and the blood vessels are also contracted, so that the technical effect of rapid hemostasis is achieved. Among them, the size, frequency and heating hemostasis time of the current are selected according to the requirement. The technical scheme of the utility model has the advantages of fast hemostasis speed, no additional compression hemostasis, avoidance of skin allergy and other related problems caused by compression hemostasis, and no bulky restraint, and the postoperative feeling is more natural.
[0037] Since the contact 1 is needed to introduce current, the doctor is unable to hold it, so in an embodiment, the hemostatic device 100 comprises an insulating shell 4, which has an open end provided with a mounting cavity 41, the contact 1 is inserted into the mounting cavity 41, and the contact 1 is at least partially located outside the mounting cavity 41 to contact the wound. By holding the insulating shell 4 to manipulate the contact 1.
[0038] In order to quickly clean the blood in the wound, facilitate the next step of hemostasis, a plurality of through holes 12 are provided on the part of the contact 1 outside the mounting cavity 41, the through holes 12 are radially arranged along the contact 1 and communicate with the suction channel 11, and a plurality of through holes 12 are arranged axially along the contact 1. A plurality of suction ports are formed by the through holes 12 for simultaneously sucking blood in the wound, thereby improving the cleaning efficiency. For the case where only one side of the tissue is injured inside the wound, if the contact 1 is inserted into the wound, not only the injured tissue will be electrocoagulated and denatured, but also the normal tissue in the wound will be electrocoagulated and denatured, so in another embodiment, the contact 1 has a first side and a second side opposite in the radial direction, the first side is provided with an insulating coating, and the second side is provided with a plurality of through holes 12, the through holes 12 communicate with the suction channel 11, and a plurality of through holes 12 are arranged axially along the contact 1. When the contact is inserted into the wound, the first side corresponds to the normal tissue, and the second side corresponds to the tissue to be electrocoagulated.
[0039] Since the utility model is by heating, make the cell protein of tissue denature, coagulation, with the shrinkage of blood vessel, thereby achieve the technical effect of fast hemostasis. When the part corresponding to the through hole 12 of the wound is not in direct contact with the contact 1, the hemostatic effect is slow, so the contact 1 is rotatably installed in the mounting cavity 41 along the axial direction. Rotating the contact 1 can make the contact 1 contact each part inside the wound, and the rotation of the contact 1 can also change the position of the through hole 12, which is also beneficial to sucking blood from each part of the wound.
[0040] The specific structure for driving the contact 1 to rotate is that the hemostatic device 100 further comprises a gear ring 5, a gear 6 and a motor 7, the gear ring 5 is sleeved on the contact 1 and located in the mounting cavity 41, the gear 6 is engaged with the gear ring 5, and the motor 7 is fixedly installed in the mounting cavity 41 and drivingly connected with the gear 6. The motor 7 drives the gear 6 to rotate, and the gear 6 drives the gear ring 5 and the contact 1 to rotate.
[0041] Since the contact 1 is conducted by an external power supply, in order to prevent current from being guided to the motor 7, one of the gear ring 5 or the gear 6 is made of insulating material, and in an embodiment, the gear 6 is made of insulating gear 6.
[0042] Because the contact 1 is rotating, if the part in contact with the contact 1 is fixed, the contact 1 or the part in contact will be out of contact after wearing, resulting in that the current cannot be guided to the contact 1. Therefore, in an embodiment, the current conducting assembly 3 comprises an abutting piece 31, a spring 32 and a plug 33, the abutting piece 31 is rotatably installed at one end of the inner side wall of the installation cavity 41; the spring 32 is fixedly connected at one end to the inner side wall of the installation cavity 41 and connected at the other end to the middle part of the abutting piece 31, and the spring 32 is in a compressed state to make the other end of the abutting piece 31 abut against the contact 1; the plug 33 is electrically connected to the abutting piece 31. When the abutting piece 31 or the contact 1 wears, the abutting piece 31 has a certain deformation capacity, and under the action of the spring 32, the spring 32 continues to press the abutting piece 31 to abut against the contact 1, thereby ensuring that the current can flow smoothly to the contact 1.
[0043] Because the contact 1 is rotating, and the pipeline connected with the negative pressure generating device 2 cannot rotate, therefore, in an embodiment, the insulating shell 4 is provided with a mounting hole 42 penetrating in the axial direction of the contact 1, and the mounting hole 42 and the opening of the installation cavity 41 are arranged in axial correspondence with the contact 1; the hemostasis device 100 further comprises a rotating joint 8, the rotating joint 8 comprises a first joint 81 and a second joint 82, the first joint 81 and the second joint 82 can rotate relative to each other and are in communication with each other, the first joint 81 is fixedly installed in the mounting hole 42, the first joint 81 is connected with the negative pressure generating device 2, and the second joint 82 is connected with the contact 1, so that the negative pressure generating device 2 is in communication with the suction passage 11.
[0044] In addition, after hemostasis contact, the device needs to be cleaned before being stored, therefore, the negative pressure generating device 2 and the first joint 81 are detachably arranged, and the hemostasis device 100 further comprises a water pump, and the water pump is detachably arranged with the first joint 81. After hemostasis contact, the negative pressure generating device 2 is detached, and the water pump is installed to clean the inside of the contact 1 by water injection.
[0045] After use, the hemostasis device 100 also needs to be stored, in order to prevent the contact 1 from being contaminated, therefore, the hemostasis device 100 further comprises a cover 9, the cover 9 is detachably arranged in the insulating shell 4 corresponding to the opening of the installation cavity 41, and the cover 9 is used to be connected with the insulating shell 4 to form a cavity, so that the part of the contact 1 located outside the installation cavity 41 is located in the cavity.
[0046] The above merely illustrates the exemplary embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields under the technical concept of the present application and by using the content of the present application specification and drawings are included in the patent protection scope of the present application.
