Description

Technical Field

[0001] The utility model belongs to the technical field of surgical thoracotomy, and particularly relates to an adjustable thoracotome. Background Art

[0002] Thoracic surgery is a medical specialty that specializes in the diagnosis and treatment of organs within the thoracic cavity, mainly referring to the esophagus, lungs, and mediastinal lesions. The field of breast surgery is also classified into this specialty, with pulmonary surgery and esophageal surgery being the main focuses. A thoracotome is one of the most important surgical instruments in general thoracic surgery, which can expand the patient's chest and assist doctors in performing surgeries inside the patient's chest.

[0003] After retrieval, for example, a Chinese patent application with the publication number CN214804988U discloses an adjustable thoracotome for thoracic surgery. In this adjustable thoracotome for thoracic surgery, by turning the knob to drive the screw rod to rotate, under the guidance of the guide rod, the movable arm can be driven to approach or move away from the fixed arm, thus achieving the purpose of support, and the operation is simple; through the elastic force of the spring, the push plate is pushed to drive the lubricating cotton to pass through the arc-shaped through groove and abut against the screw rod. The lubricating oil inside the oil storage box soaks into the lubricating cotton through the oil guide cotton core. When the housing moves along with the movable arm, the lubricating cotton rubs against the screw rod to achieve lubrication of the screw rod and prevent the screw rod from rusting and blocking, which makes it difficult to move and adjust the movable arm. However, after the above-mentioned solution is used, the storage space occupied is relatively large, affecting storage; moreover, the support flap of the above-mentioned solution is fixed at one end of the movable arm, so in order to avoid contamination during the next use, the overall structure needs to be carefully disinfected, which is rather troublesome.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the field of surgical thoracotomy without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figure 1 and 2 shown, the present invention provides an adjustable thoracotome, including an outer shell 1. A sliding cavity 5 is opened inside the outer shell 1. Two lead screw sliders 7 are movably arranged inside the sliding cavity 5. A movable arm 8 is movably arranged on one side of the lead screw slider 7. A support flap 9 is movably arranged at one end of the movable arm 8. A bi-directional lead screw 6 is movably arranged inside the sliding cavity 5. Both ends of the bi-directional lead screw 6 respectively penetrate through both ends of the inner wall of the sliding cavity 5. A rotary knob 4 is fixedly arranged at one end of the bi-directional lead screw 6. The outer surface of the bi-directional lead screw 6 is threadedly connected with the inner side of the lead screw slider 7.

[0021] In order to reduce the occupied space and make storage more convenient, folding and storage devices 2 are respectively arranged on one side of the two lead screw sliders 7 for folding and storing the movable arms 8.

[0022] As Figure 3As shown in the figure, the folding and storage device 2 includes a hinge seat 21 fixedly arranged on one side of the lead screw slider 7. A rotating block 23 is movably arranged inside the hinge seat 21. Limiting holes 22 are respectively opened at the upper and lower ends of the hinge seat 21. Two elastic chambers 24 are opened inside the rotating block 23. One side of the rotating block 23 is fixedly connected to one end of the movable arm 8. A micro spring 25 and a limiting convex block 26 are movably arranged inside the elastic chamber 24. The limiting convex block 26 protrudes from the inside of the elastic chamber 24. The limiting convex block 26 is adapted to the limiting hole 22. Through the cooperation of the bidirectional lead screw 6 and the lead screw slider 7, the two lead screw sliders 7 can be driven to move. During storage, the two lead screw sliders 7 are centered and moved closer. Through the micro spring 25 and the limiting convex block 26, the storage and protrusion of the limiting convex block 26 can be realized. When folding and storing, the two limiting convex blocks 26 are pressed out of the two limiting holes 22, the movable arm 8 is rotated, and the two limiting convex blocks 26 protrude in the other two limiting holes 22, so as to realize the folding of the movable arm, overall reducing the occupied space and making storage more convenient.

[0023] Meanwhile, in order to improve the use safety and avoid wound infection caused by repeated use, a convenient replacement device 3 for assembling or replacing the support flap 9 is provided at one end of the movable arm 8.

[0024] As Figure 4 shown, the convenient replacement device 3 includes a storage cavity 32 opened at one end of the movable arm 8. An adjusting end 33 is hinged inside the storage cavity 32. Two anti-slip pads 34 are fixedly arranged on both sides of the inner wall of the storage cavity 32 and are respectively located on both sides of the adjusting end 33. An assembling block 35 is fixedly arranged at the lower end of the adjusting end 33. Second slots 37 are opened on both sides of the assembling block 35. An installation cavity 36 is opened at the lower end of the assembling block 35. An inserting block 38 is fixedly arranged at the upper end of the support flap 9. A first slot 31 is opened inside the inserting block 38. The inserting block 38 is adapted to the installation cavity 36. The diameters of the first slot 31 and the second slot 37 are the same. Through the cooperation of the adjusting end 33 and the storage cavity 32, when not in use, the adjusting end 33 can be stored. When in use, by using the cooperation of the adjusting end 33 and the anti-slip pads 34, rotation adjustment can be realized. The inserting block 38 is inserted into the installation cavity 36, and then bolts are passed through the first slot 31 and the second slot 37, so as to realize the effect of installing the support flap 9. The support flap 9 is a disposable item and can be separately removed and replaced, improving the use safety and avoiding wound infection caused by repeated use.

[0025] When the adjustable chest opener is used, the two movable arms 8 are unfolded by using the folding storage device 2, and the disposable support flaps 9 are installed by using the convenient replacement device 3. The two support flaps 9 are inserted between the patient's ribs, and the knob 4 is turned to cooperate with the screw slider 7 and the bidirectional screw 6 to open the patient's chest. After use, the support flaps 9 are removed, and the two movable arms 8 are stored by using the folding storage device 2, which improves the practicality of the utility model as a whole, reduces the occupied space during storage, and uses the disposable support flaps 9 to improve the safety of use and avoid the risk of infection of the patient's wound.
