[0050] As used in this specification and the appended claims, the singular forms "a", "an" and "the" include plural referents unless the content clearly dictates otherwise. It should be noted that the term "comprising" typically is used in its inclusive sense, unless the context clearly dictates otherwise.

[0051] In the following description, for purposes of clarity, directional terms are used, such as forward, rearward, left, right, outer, inner, outwardly, inwardly, above, below, etc. These and similar terms are not to be construed as limiting but are intended to reflect the relative positions and / or orientations of the components illustrated in the drawings.

[0052] The present application relates to a surgical assisting device 100, which comprises a shield member 1 and a blade member 2, the shield member 1 extends along a first direction X and has a distal end 11 and a proximal end 12 along the first direction X, the distal end 11 of the shield member 1 is used to go inside a patient incision 4, and the proximal end 12 is closer to the outside of the incision 4 than the distal end 11. The patient incision 4 also extends along the first direction X, and there is a lesion target area 6 inside the incision 4. The shield member 1 of the present application is used to fit the tissue 5 on both sides of the incision 4 along the second direction, so as to pull away the tissue 5 such as muscle, organ, etc. around the incision 4, so as to expose the lesion target area 6.

[0053] The blade member 2 comprises an adjusting part 21 and a fixed part, the adjusting part 21 extends along the first direction X and has a distal end which is adjustably connected with the proximal end 12 of the shield member 1 along the first direction X, and a proximal end which is located outside the patient incision 4 and is connected with the fixed part.

[0054] Generally, two assisting devices 100 are needed to support the incision 4 inside the patient incision 4, such as Figure 8As shown, the two protection parts 1 of the two auxiliary devices 100 are oppositely arranged along the second direction Y, and the two protection parts 1 oppositely push apart the two sides of the incision 4 of the patient along the second direction Y to form a field of view for the doctor to operate.

[0055] The total length of the adjustment part 21 and the protection part 1 needs to be adjusted according to the depth of the incision 4 of the patient, so that the auxiliary device 100 of the present application can be adapted to surgeries of incisions 4 of various depths, and in addition, the fixing part is located outside the incision 4 and can be held by hand or fixed to the skin of the patient.

[0056] In one embodiment, the protection part 1 is provided with a threaded hole 13, and the protection part 1 is adjustably connected with the adjustment part 21 through an adjusting bolt 3.

[0057] Specifically, as shown in the drawings, Figures 1-3 the end surface of the proximal end 12 of the protection part 1 is provided with a threaded hole 13, and the adjustment part 21 is provided with a collar 211, the distal end of the adjusting bolt 3 passes through the collar 211 of the adjustment part 21 and is threadedly connected with the threaded hole 13 of the protection part 1, and the distal end of the adjusting bolt 3 is located outside the proximal end 12 of the adjustment part 21. The adjusting bolt 3 can be driven to rotate by using a screwdriver 8, and the protection part 1 is driven to move along the first direction X.

[0058] The adjusting bolt 3 and the collar 211 are rotatably connected, or a bearing can be installed in the collar 211, and the adjusting bolt 3 is connected with the bearing.

[0059] As a preferred solution, one of the protection part 1 and the adjustment part 21 is provided with a first sliding groove 14 extending along the first direction X, and the other is provided with a first guide rod 212 extending along the first direction X, and the first guide rod 212 is slidably installed in the first sliding groove 14.

[0060] In the embodiment shown in the drawings, Figures 1-3 two first sliding grooves 14 are arranged on the protection part 1 and located on both sides of the threaded hole 13, and two first guide rods 212 are located on both sides of the adjusting bolt 3 and are slidably connected with the two first sliding grooves 14 along the first direction X.

[0061] It should be understood that in other embodiments, the adjustment part 21 extends along the first direction X and is provided with the above-mentioned first sliding groove 14, and the protection part 1 includes a plurality of first guide rods 212, and the plurality of first guide rods 212 can slide along the first direction X along the first sliding groove 14, which can also achieve the adjustment of the total length of the adjustment part 21 and the protection part 1 along the first direction X.

[0062] The number of the first guide rods 212 and the first sliding grooves 14 is not limited, and three or four can be arranged, which can be set according to the needs.

[0063] As a preferred embodiment, one of the protective component 1 and the adjustment part 21 is provided with a second slide groove 15 along the first direction X, and the other is provided with a second guide rod 213 extending along the first direction X. The second guide rod 213 is slidably installed in the second slide groove 15 and is provided with scale markings 214.

[0064] exist Figures 2-4 In the embodiment shown, two first grooves 14 are located on the protective member 1 and are formed by the proximal end 12 of the protective member 1, and two second grooves 15 are located on both sides of the two first grooves 14.

[0065] The two second guide rods 213 are located outside the two first guide rods 212, and the two second guide rods 213 are slidably installed in the two second slide grooves 15.

[0066] The two second guide rods 213 are each equipped with a scale mark 214, which can be used to determine the distance from the patient's body surface to the surgical operation position.

[0067] In addition, the two second guide rods 213, the adjusting bolt 3, and the two first guide rods 212 are arranged side by side in an outwardly concave arc shape.

[0068] Specifically, the protective component 1 has an outer side 16 and an inner side 17 along the second direction Y. Its outer side 16 fits the tissue 5 at the incision 4. When the two protective components 1 are placed, the opposite side of the two protective components 1 is the inner side 17.

[0069] Two second guide rods 213, adjusting bolts 3 and two first guide rods 212 are arranged in an arc shape that is concave to the outside 16. When the two protective components 1 are set opposite each other, both protective components 1 are concave to both sides of the incision 4. The two protective components 1 are spaced apart to form a larger clearance space, which makes it easier for doctors to observe the target area 6 of the lesion.

[0070] The distal end 11 of the protective component 1 is also provided with an outwardly protruding flange 18. The flange 18 protrudes toward the outer side 16 of the protective component 1 to support the tissues 5 on both sides of the incision 4 and prevent the end face of the distal end 11 of the protective component 1 from squeezing the tissues 5 near the target area 6 of the lesion. The flange 18 can support the tissues 5 of the target area 6 of the lesion and make them slightly close to the second direction Y, so as to avoid curling the end face of the distal end 11 of the protective component 1 during traction.

[0071] exist Figures 1-4 In the embodiment shown, the adjustment part 21 includes two first guide rods 212 and two second guide rods 213, and the fixing part is a blade 22. The blade 22 is disc-shaped and connected to the adjustment part 21 in an L-shape. One end of the blade 22 along the second direction Y is fixedly connected to the adjustment part 21, and the other end extends along the second direction Y. The blade 22 and the adjustment part 21 are preferably integrally formed.

[0072] The blade 22 is disc-shaped with a relatively large surface area, which can be fixed to the skin outside the patient's incision 4. Specifically, it can be glued to the patient's skin or fitted with a telescopic strap to fix it to the patient's waist or limbs. Different fixation methods can be used depending on the type of surgery.

[0073] The blade 22 is preferably made of aluminum alloy with a certain deformation, which can conform to human skin and adhere to the skin. In addition, silicone can be applied to the outer surface of the blade 22 to increase comfort.

[0074] Optionally, the blade 22 can also be made of plastic, with a certain thickness and deformation. The end of the blade away from the adjustment part 21 can also be set to be slightly bent downwards to further grip the skin and prevent it from shifting.

[0075] exist Figures 5-7 In the embodiment shown, the adjustment part 21 also consists of two first guide rods 212 and two second guide rods 213, while the fixing part is a handheld blade 23. The handheld blade 23 extends along the second direction Y and has a certain length. The handheld blade 23 is also integrally formed with the adjustment part 21. The handheld blade 23 is used for clinical situations where handheld use is required.

[0076] The protective component 1 is also provided with an anti-detachment part 7, which is arranged around the proximal end 12 of the protective component 1. Since the openings of the first slide groove 14 and the second slide groove 15 are both located at the proximal end 12 of the protective component 1, the openings of the first slide groove 14 and the second slide groove 15 are prone to deformation during use, which increases the size of the openings of the first slide groove 14 and the second slide groove 15. In order to prevent the openings of the first slide groove 14 and the second slide groove 15 from increasing and to prevent the first guide rod 212 and the second guide rod 213 from sliding along the first direction X and detaching from the openings of the first slide groove 14 and the second slide groove 15 of the protective component 1, it is necessary to control the deformation of the proximal end 12 of the protective component 1. Therefore, the anti-detachment part 7 is provided to control the deformation of the protective component 1.

[0077] The auxiliary device 100 of the present invention can be matched with clinical patients of different body types during surgery, and the blade 22 can be fixed on the patient's body surface by means of a film, freeing up the assistant's operation and effectively reducing the operation time.

[0078] The adjusting part 21 and the protection part 1 can be adjusted by controlling the adjusting bolt 3 to adjust the length of the adjusting part 21 and the protection part 1 to the length required by the clinic, so that they can be conveniently matched with patients with different body shapes during the operation, and they can reflect the distance of the skin from the operation position, providing a basis for the length of the instruments used by the doctor subsequently. The blades 22 can be fixed to the body surface of the patient by means of a film to achieve stable and controllable traction, completely freeing the hands of the assistant. At the same time, it effectively avoids unnecessary compression, friction or tearing caused by repeated replacement of the blades 22 during the operation, significantly reducing postoperative complications such as nerve paralysis and tissue edema. Not only does it improve the safety and accuracy of the operation, but it also creates a more relaxed operating environment for the doctor, which is an important part of ensuring the success of the operation.

[0079] In a preferred embodiment, the surgical auxiliary device further comprises a mounting part 9 which can be connected with the protection part or the blade part for mounting the light source device 101 or the drainage device 102, or simultaneously mounting the light source device 101 and the drainage device 102.

The relief hole is used to avoid the screw rod of the locking bolt 94, and the threaded hole is used to mount the screw rod of the locking bolt.

[0084] AsFigure 14 As shown, the pressing plate 93 is in a sheet shape and has a certain deformation amount, and the pressing plate 93 includes a connecting piece 931 and two driving pieces 932, the connecting piece 931 extends along the third direction Z and two ends of the connecting piece 931 are connected with the two driving pieces 932 respectively. The two driving pieces are close to the two mounting holes 91 respectively.

[0085] The screw rod of the locking bolt 94 includes a first section 941 and a second section 942, the first section is located at an end of the screw rod away from the nut and is provided with a thread, and the first section 941 is threadedly connected with the threaded hole of the clamping plate. The second section 942 is close to the first section and is located between the two clamping plates 92, and the diameter of the second section 942 gradually increases from the distal end to the proximal end, that is, the diameter of the second section gradually increases from the lower part to the upper part, and the cross section of the second section along the first direction is in a trapezoidal structure.

[0086] The locking bolt 94 passes through the avoiding hole and enters the threaded hole of the clamping plate, is threadedly connected with the clamping plate, and the second section is located between the two clamping plates, and the nut is located outside the proximal clamping plate, that is, above the clamping plate at the top.

[0087] The second section 942 is located between the two driving pieces 932, and rotating the nut can make the screw rod move downward, so that the second section 942 drives the two driving pieces 932 to move toward the two mounting holes 91, thereby tightening the pipeline of the light source device and the drainage device.

[0088] It should be understood that in another embodiment, a threaded hole can also be arranged in an upper clamping plate, the first section of the locking bolt is located above the second section, the second section is also located between the two clamping plates, the first section is located in the threaded hole of the upper clamping plate and is threadedly connected with the clamping plate, and rotating the locking bolt can also drive the two driving pieces to move toward the two mounting holes.
