Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an auxiliary device for surgical procedures. Background Technology

[0002] In modern surgery, the protection of exposed soft tissues requires a key auxiliary instrument whose core function is to provide a safe, clear, and stable field of vision for the operation.

[0003] In deep laparoscopic or open surgery, the surgeon needs to pull apart the muscles, organs and other tissues around the incision to expose the target area of ​​the lesion.

[0004] Traditional surgical devices require an assistant to manually hold the retractor and pull away muscles, organs, and other tissues around the incision. This is not only laborious and unstable, but also prone to displacement due to fatigue. More importantly, the hard edges of the retractors can cause continuous pressure damage to the pulled tissues, such as nerves, blood vessels, and internal organs. Furthermore, due to the diverse body shapes of patients, different sizes of devices are usually required to match each patient, leading to cumbersome procedures, prolonged operation time, and increased intraoperative blood loss.

However, terms such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and not as limiting terms.

[0052] This utility model relates to a surgical auxiliary device 100, which includes a protective component 1 and a blade component 2. The protective component 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 protective component 1 is used to penetrate into the patient's incision 4, and the proximal end 12 is closer to the outside of the incision 4 than the distal end 11. The patient's incision 4 also extends along the first direction X, and the lesion target area 6 is inside the incision 4. The protective component 1 of this utility model is used to conform to the tissues 5 on both sides of the incision 4 along a second direction, pulling away the muscles, organs, and other tissues 5 around the incision 4 to expose the lesion target area 6.

[0053] The blade component 2 includes an adjustment part 21 and a fixing part. The adjustment part 21 extends along a first direction X and its distal end is adjustablely connected to the proximal end 12 of the protective component 1 along the first direction X. The proximal end is located outside the patient incision 4 and is connected to the fixing part.

[0054] Generally, the patient needs two auxiliary devices 100 to support the incision 4, such as... Figure 8 As shown, the protective components 1 of the two auxiliary devices 100 are arranged opposite each other along the second direction Y. The two protective components 1 open the patient's incision 4 on both sides along the second direction Y to form a field of vision that is convenient for the doctor to operate.

[0055] The total length of the adjustment part 21 and the protective part 1 needs to be adjusted according to the depth of the patient's incision 4, so that the auxiliary device 100 of this utility model can be adapted to surgery with incisions 4 of various depths. In addition, the fixing part is located outside the incision 4. The fixing part can be held by hand or fixed to the patient's skin.

[0056] In one embodiment, the protective component 1 is provided with a threaded hole 13, and the protective component 1 is adjustablely connected to the adjusting part 21 by an adjusting bolt 3.

[0057] Specifically, such as Figure 1-3 As shown, the end face of the proximal end 12 of the protective component 1 is provided with a threaded hole 13, and the adjusting part 21 is provided with a retaining ring 211. The distal end of the adjusting bolt 3 passes through the retaining ring 211 of the adjusting part 21 and is threadedly connected to the threaded hole 13 of the protective component 1. The distal end of the adjusting bolt 3 is located outside the proximal end 12 of the adjusting part 21. The adjusting bolt 3 can be driven to rotate using a screwdriver 8, thereby driving the protective component 1 to move along the first direction X.

[0058] The adjusting bolt 3 is rotatably connected to the retaining ring 211, or a bearing can be installed inside the retaining ring 211, and the adjusting bolt 3 is connected to the bearing.

[0059] As a preferred embodiment, one of the protective component 1 and the adjusting part 21 is provided with a first slide 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. The first guide rod 212 is slidably installed in the first slide groove 14.

[0060] exist Figure 1-3 In the embodiment shown, two first slide grooves 14 are disposed on the protective component 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 respectively slidably connected to the two first slide 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 first slide groove 14 described above. The protective component 1 includes a plurality of first guide rods 212. The plurality of first guide rods 212 can slide along the first slide groove 14 along the first direction X, and can also realize the adjustment of the total length of the adjustment part 21 and the protective component 1 along the first direction X.

[0062] The number of the first guide rod 212 and the first slide groove 14 is not limited; three or four can be set, depending on the requirements.

[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 Figure 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 Figure 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 Figure 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 this invention can be matched with clinical patients of different body types during surgery. At the same time, the blade 22 can be fixed to the patient's body surface by means of a film, freeing up the assistant's operation and effectively reducing the operation time.

[0078] The adjustment section 21 and protective component 1 are adjustable. The length of the adjustment section 21 and protective component 1 can be adjusted to the required clinical length via the control adjustment bolt 3, allowing for convenient matching with patients of different body shapes during surgery. Simultaneously, it reflects the distance between the skin and the surgical site, providing a basis for the surgeon to determine the length of instruments to use later. The blade 22 can be fixed to the patient's skin surface via a film, achieving stable and controllable traction, completely freeing the assistant's hands. It also effectively avoids unnecessary compression, friction, or tearing caused by repeated replacement of the blade 22 during surgery, significantly reducing postoperative complications such as nerve paralysis and tissue edema. This not only improves the safety and precision of the surgery but also creates a more comfortable operating environment for the surgeon, making it a crucial element in ensuring surgical success.

[0079] In a preferred embodiment, the surgical aid further includes a mounting part 9, which can be connected to a protective component or a blade component for mounting a light source device 101 or a drain 102, or simultaneously mounting the light source device 101 and the drain 102.

[0080] The light source is typically a light strip, used for surgical illumination, while the drainage device is used for intraoperative fluid flushing. Generally, two surgical aids are needed during surgery: one for flushing and cleaning, and the other for drainage.

[0081] The mounting part 9 is preferably connected to the proximal end of the adjusting part 21. Figure 9 and 11 In the embodiment shown, the mounting part is installed near the adjustment part. The mounting part has two mounting holes 921, one of which is used to install the light source device 101 and the other is used to install the drainer 102. The drainer's pipe can be fixed in the mounting hole.

[0082] Furthermore, such as Figure 9-12 As shown, the mounting part includes two clamping plates 92 and fasteners. The fasteners include a pressure plate 93 located between the two clamping plates 92 and a locking bolt 94. The two clamping plates 92 are arranged opposite each other along the first direction X and are spaced apart. The two clamping plates 92 are provided with mounting holes 91 at both ends along the third direction Z. The two mounting holes 91 are connected to the gap between the two clamping plates 92.

[0083] Of the two clamping plates 92, the one closer to the far end has a threaded hole, and the other clamping plate has a clearance hole. Figure 9 and 11 In the embodiment shown, the lower clamping plate 92 is provided with a threaded hole, and the upper clamping plate is provided with a clearance hole. The clearance hole and the screw hole are aligned along a first direction, that is, aligned along the vertical direction. The clearance hole is used to avoid the screw of the locking bolt 94, while the threaded hole is used to install the screw of the locking bolt.

[0084] like Figure 14 As shown, the pressure plate 93 is sheet-shaped and has a certain deformation. The pressure plate 93 includes an integrally formed connector 931 and two driving members 932. The connector 931 extends along the third direction Z and its two ends are respectively connected to the two driving members 932. The two driving members are respectively adjacent to two mounting holes 91.

[0085] The locking bolt 94 has a first section 941 and a second section 942. The first section is located at the end of the bolt furthest from the nut and is threaded. The first section 941 is threadedly connected to the threaded hole of the clamping plate. The second section 942 is adjacent to the first section and located between the two clamping plates 92. The diameter of the second section 942 gradually increases from the far end to the near end, that is, the diameter of the second section gradually increases from bottom to top. The cross-section of the second section along the first direction is a trapezoidal structure.

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

[0087] The second segment 942 is located between the two drive members 932. Rotating the nut causes the screw to move downward, thereby causing the second segment 942 to drive the two drive members 932 to move toward the two mounting holes 91, thus tightening the pipes of the light source device and the drain.

[0088] It should be understood that in another embodiment, a threaded hole can also be provided on the upper clamping plate, the first segment of the locking bolt is located above the second segment, the second segment is also located between the two clamping plates, the first segment is located in the threaded hole of the upper clamping plate and is threadedly connected to the clamping plate, and the rotation of the locking bolt can also drive the two driving components to move toward the two mounting holes.

[0089] In other embodiments, the fastener may also be configured as a spring wire located within two mounting holes, the spring wire being elastic and capable of securing the drainer or light source device.

[0090] This invention provides an adjustable-length surgical aid device 100, which can be matched with clinical patients of different body types during surgery. At the same time, it can reflect the distance between the skin and the surgical site, providing a basis for doctors to judge the length of instruments to be used later. It can also be fixed to the patient's body surface by means of a film, freeing up the assistant to operate and effectively reducing the operation time.

[0091] The fixation part has a blade 22 with a sheet-like film structure and a handheld blade 23 with a handheld structure, which can meet different clinical needs.

[0092] The preferred embodiments of the present invention have been described in detail above, but it should be understood that, if necessary, aspects of the embodiments can be modified to utilize aspects, features, and concepts from various patents, applications, and publications to provide other embodiments.

[0093] In light of the detailed description above, these and other changes can be made to the embodiments. Generally, the terminology used in the claims should not be considered limited to the specific embodiments disclosed in the specification and claims, but should be understood to include all possible embodiments together with the full scope of equivalents enjoyed by these claims.

[0094] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
