Description

Wound contraction auxiliary system

Technical Field

The invention relates to the technical field of medical instruments, in particular to a wound contraction assisting system.

Background

Skin tissue, which is the outermost natural protective layer of the human body, is a common medical operation in medical operation treatment due to various diseases or sudden conditions, and modern medicine generally treats skin wounds by means of needle and thread suturing. However, despite the continuous progress of modern medical technology, scars are left after the wound is healed after the suture with the needle and the thread, which affects the beauty. Especially for wounds with a large area, such as for example after a caesarean section of a parturient, the healed scar remains on the belly, even if it has healed. And because the wound area left on the belly by caesarean section is large and long in size, the area of the healed scar is larger, the size of the scar is also longer, and certain influence is caused on the beauty of the skin of the human body.

In the conventional medical technology, in order to promote the healing of a wound, a skin lesion therapeutic body is generally attached to the wound site. Among them, in the case of a skin wound formed on the belly by a caesarean section, since the skin wound by the caesarean section is transversely cut, a conventional body for treating skin damage is generally attached to the upper and lower surfaces of the skin wound to prevent the skin wound from being re-opened. However, such a body for treating skin lesions cannot reduce the length of the skin wound in the transverse direction, and therefore, a long scar remains on the healed skin wound. In addition, the traditional body for treating skin damage is generally only suitable for skin wounds with regular incisions like caesarean section, and for skin wounds which are complex and have special wound positions, the traditional body for treating skin damage is not well suitable and has unobvious treatment effect. Therefore, the body for treating skin damage can prevent the wound from reopening to some extent. However, the body for treating skin lesions cannot be well adapted to skins of different positions and sizes, and mainly helps the healing of wounds by being attached to the wound site to inhibit the stretching of the skin, but cannot reduce the length or area of scars. In addition, some skin wounds with special wound positions and large or irregular areas are not easy to attach to the wound positions, and the skin injury treatment body cannot help wound healing. Therefore, it is not in accordance with the actual medical needs.

Through setting up propelling part group and locking wire mechanism, play the effect of fixed and shrink wire to guarantee that the wire has the contractile force to the wound. Specifically, in the process of slowly repairing the wound, the length of the skin wound can be gradually contracted, and the skin slowly closes the wound under the change of the length of the wound, so that the effect of reducing scars is achieved. The thread locking mechanism is detachably arranged on the propelling part group, when the thread locking mechanism is detached, the thread locking mechanism simultaneously loosens acting force on the metal wire group, the two end parts of the metal wire group are lifted and pulled outwards, the propelling part group on the metal wire group can be pulled to be close to each other, the distance between wounds is reduced, when the thread locking mechanism is fixed on the propelling part group, the metal wire group is also locked on the thread locking mechanism, and therefore the wounds after contraction are fixed, and the size of the wounds is reduced gradually in the wound repairing process by utilizing the elasticity of skin and the self-repairing function.

Wherein, this technical scheme has set up two sets of metal wires and two sets of propulsion pieces, through controlling pulling metal wire and propulsion piece, enables that skin contracts more evenly, stably.

Among this technical scheme, the two tip of first metal wire is through the locking wire mechanism chucking on the first propulsion spare, and the locking wire mechanism chucking of second propulsion spare is passed through at the two tip of second metal wire, loosens the back of wire group when locking wire mechanism, through the pulling metal wire, can be with first propulsion spare and second propulsion spare toward the wound and draw close, and then taut skin reduces the size of wound, makes the wound shrink gradually at the repair in-process, and the scar that finally forms is less than the size of original wound.

Furthermore, the interior of the propelling piece group is of a hollow structure, the wire locking mechanism comprises a fixing piece and a first stud, the fixing piece is fixed in the hollow structure, the inner wall of the propelling piece group is provided with threads, and the first stud is in threaded connection with the propelling piece group and abuts against the fixing piece; and two end parts of the metal wire group are locked between the fixing piece and the first stud after penetrating through the threading through holes of the propelling piece group.

In this technical scheme, the same threading through-hole of first propelling part is passed at the both ends of first metal wire, and a terminal surface of mounting just is located the below of this threading through-hole, and when first double-screw bolt was screwed in first propelling part, contradicted to a terminal surface of mounting to with the both ends chucking of first metal wire between first double-screw bolt and mounting. Similarly, two end parts of the second metal wire penetrate through the same threading through hole of the second propelling part and are clamped between the first stud and the fixing part in the second propelling part.

Furthermore, after threading, the pulling force ends of the first pushing piece are concentrated at the two end parts of the first metal wire, and the pulling force ends of the second pushing piece are concentrated at the two end parts of the second metal wire, so that the pulling forces of the two pushing pieces are more even, and the first pushing piece and the second pushing piece are arranged in a reverse direction. Specifically, the left and right sides of the wound are provided with the position reference datum by the propelling part group, wherein the threading through holes in the propelling part group are sequentially arranged on the propelling part from top to bottom, the pulling force end of the first propelling part is arranged in the first threading through hole above the first propelling part, and the pulling force end of the second propelling part is arranged in the last threading through hole arranged on the second propelling part from top to bottom, so that the stress of the propelling part group is more uniform, the stress of the wound is also uniform, and the contraction and recovery of the wound are more facilitated.

Furthermore, a wire winding mechanism is further arranged inside the propelling piece group, the wire winding mechanism is provided with a threading through hole, and the first metal wire sequentially passes through the second propelling piece and the threading through hole of the wire winding mechanism inside the second propelling piece; the second metal wire sequentially penetrates through the first propelling piece and the threading through holes of the winding mechanism in the first propelling piece, and when the winding mechanism is rotated, the metal wire group is wound on the winding mechanism along with the rotation of the winding mechanism, so that the wound is contracted.

The coiling mechanism can coil the metal wire, and the length of the coiling mechanism coiling the metal wire once is known, so that the metal wire can be shortened more accurately by the arrangement of the coiling mechanism, and the size of a wound is reduced. The wire is retracted by the wire winding mechanism, and the trouble of adjusting by loosening or screwing the first stud every time is avoided. Specifically, after the two end portions of the metal wire are fixed by the first stud and the fixing member for the first time, the metal wire can be subsequently contracted by rotating the wire coiling mechanism.

Further, the length of the winding metal wire is 1-2 mm when the winding mechanism rotates for one circle. The total contraction length of the metal wire can be controlled by controlling the rotation number of the wire coiling mechanism.

Specifically, the first metal wire is wound through a winding mechanism inside the second propelling piece, and the second metal wire is wound through a winding mechanism inside the first propelling piece. Due to the tightening of the metal wire, the skin of the wound is also tightened, which is beneficial to reducing the size of the wound.

Furthermore, an elastic piece is further arranged inside the propelling piece group, and the elastic piece is arranged between the fixing piece and the winding mechanism and used for compressing and fixing the winding mechanism after winding.

In the technical scheme, the elastic piece is a spring, and the elastic piece further compresses the winding mechanism through elasticity, so that the winding mechanism is prevented from rotating under the action of a metal wire after winding.

The winding mechanism is provided with an auxiliary rotating groove, the second stud is provided with a hollow channel, and the hollow channel penetrates through the position of the rotating groove.

The second stud is used for further pressing the wire coiling mechanism. The hollow channel arranged on the second stud facilitates an operator to rotate the wire winding mechanism by using an external auxiliary rotating tool under the condition that the second stud is not detached. The rotation groove on the winding mechanism can be used as a rotation supporting part to assist rotation. After the rotation, the second stud bolt can be further screwed, so that the wire winding mechanism after wire winding is locked to the maximum extent.

Furthermore, the winding mechanism comprises a winding part and limiting parts arranged at two ends of the winding part, and the size of each limiting part is larger than that of the winding part and used for limiting the wound metal wire; and the wire winding part is provided with a threading through hole.

In the technical scheme, when the first metal wire penetrates into the threading through hole of the second propelling piece, the first metal wire firstly penetrates through the threading through hole on the wire winding part and then penetrates out of the other threading through hole of the second propelling piece. When the second metal wire penetrates into the threading through hole of the first pushing piece, the second metal wire firstly penetrates through the threading through hole on the wire winding part and then penetrates out of the other threading through hole of the first pushing piece. The limiting part prevents the metal wire from falling off from the winding part in the winding process.

Furthermore, a limiting part adjacent to the elastic part is a bearing part, and a rotating groove for assisting rotation is arranged on the other limiting part.

The bearing member is provided to facilitate the rotation of the winding mechanism, thereby making the rotation smoother and preventing the elastic member from being influenced by the winding mechanism to rotate.

Furthermore, the metal wire group is divided into an inner skin section metal wire and an outer skin section metal wire according to whether the metal wire group is in contact with the wound or not, the inner skin section metal wire is positioned between the two propelling pieces, arranged below the wound and enveloped in a suture line of the wound; the skin outer section metal wire is positioned on the outer sides of the two propelling pieces and is positioned on the outer side of the wound.

Preferably, there are 3 or 4 threading holes provided in the set of pushers. In order to make the skin tension above and below the wound more uniform, the first propelling part and the second propelling part are arranged in opposite directions. I.e. the sequence of the threading through holes on the first pusher is in the opposite direction to the sequence of the threading through holes on the second pusher.

For example, when 3 threading through holes are arranged on the pushing element group, the sequence of the 3 threading through holes on the first pushing element from top to bottom is one, two and three, the sequence of the 3 through holes on the second pushing element from top to bottom is three, two and one, the positions of the two threading through holes correspond to the positions of the wire coiling mechanism in the pushing element, and the positions of the three threading through holes correspond to the positions of the fixing element and the first stud; specifically, when the first metal wire passes through one threading through hole on the second pushing member, the first metal wire passes through two winding through holes of the winding mechanism in the second pushing member and finally passes through two threading through holes on the second pushing member, two end portions of the first metal wire are fixed to three threading through holes on the first pushing member, and the same applies to the second metal wire. Therefore, the first metal wire and the second metal wire are arranged up and down between the propelling piece groups, the upper end part and the lower end part of the propelling piece groups are accepted more uniformly, and the two ends of the wound are stressed more uniformly.

For example, when the pushing element group is provided with 4 threading through holes, the sequence of the 4 threading through holes on the first pushing element from top to bottom is one, two, three and four, and the sequence of the 4 through holes on the second pushing element from top to bottom is four, three and one, specifically, after the first metal wire passes through the three threading through holes on the second pushing element, one end of the first metal wire firstly passes through the four threading through holes of the first pushing element, then passes through the threading through hole of the first pushing element from the inside of the first pushing element, and is converged with the other end of the first metal wire, and then is clamped and fixed by the first stud and the fixing element between the threading through holes of the first pushing element. The same applies to the second metal line. Such threading also allows the upper and lower ends of the pusher group to be more evenly stressed. And meanwhile, the work of the wire winding mechanism is not influenced.

Furthermore, one end of the propelling piece group is locked through the first stud and the fixing piece, and the other end of the propelling piece group is wound through the winding mechanism.

The rubber sleeve is arranged to further protect the skin, and the pushing piece and the book sewing mechanism are prevented from contacting the skin and rubbing the skin.

Furthermore, puncture needles for assisting the metal wires in skin puncture are arranged at two end parts of the metal wire set, and the puncture needles can be cut off after puncture so as to avoid the puncture needles from accidentally injuring the skin. Alternatively, an external hollow lead wire may be used to assist the wire in performing the skin puncture.

Furthermore, the mutually abutted surfaces between the first stud and the fixing piece are frosted surfaces. The abrasive surface has a greater friction force to better hold the two ends of the wire set.

Furthermore, the outer end part of the first stud is of an inwards concave structure, and the inwards concave structure is of a polygonal column structure. The concave polygon prism structure is arranged, so that medical staff can insert the polygon prism structure through an external screwing piece to screw the first stud, the first stud can be miniaturized, and the human body can be prevented from feeling that foreign matters collide with the stud to the maximum extent.

Furthermore, one end part of the fixing part, which is in contact with the elastic part, is provided with a concave structure for accommodating the elastic part, and when the elastic part is compressed, at least part of the elastic part is accommodated in the concave structure of the fixing part.

Compared with the prior art, the invention has the beneficial effects that:

according to the invention, the two metal wires are arranged between subcutaneous tissues of the wound, and the metal wires and the contracted wound are fixed through the propelling piece group and the wire locking mechanism, so that the skin of the wound can be effectively contracted, the length of the skin wound can be reduced, the acting force of the metal wires can be uniformly transmitted to each position in the middle of the wound from two sides of the wound, the wound is contracted and stressed uniformly, and the effects of reducing the wound and reducing the formation of scars in the wound recovery process are facilitated.

Similarly, the two ends of the second wire 220 pass through the skin on the two sides of the wound, and then are gathered in a hole of the second pushing member 120, and are locked and fixed together by the first stud 300 and the fixing member 400 in the second pushing member 120.

The technical scheme is suitable for the condition that the wound of the skin is large, and the two holes and the four holes are separated by three holes in the middle, so that the distance between the two holes and the four holes is large, and the technical scheme is suitable for shrinking the skin with the large wound to reduce the size of the wound.

Example 5

As shown in fig. 5, the wound contraction assisting system of this embodiment is different from that of embodiment 1 in that 4 threading holes are provided in the pusher group of this embodiment. The threading through holes on the first pushing member 110 are sequentially one hole, two holes, three holes and four holes from top to bottom on the first pushing member 110, and the threading through holes on the second pushing member 120 are sequentially four holes, three holes, two holes and one hole from top to bottom on the second pushing member 120.

Further, one end of the first metal wire 210 directly penetrates into one hole of the first pushing member 110, and the other end of the first metal wire penetrates through four holes of the first pushing member 110, then penetrates out of the three holes, and then penetrates into one hole of the first pushing member 110 from the outer wall of the first pushing member 110, and after being converged with one end of the first metal wire 210, the first metal wire is locked and fixed together by the first stud 300 and the fixing member 400 in the first pushing member 110. Similarly, one end of the second metal wire 220 directly penetrates through one hole of the second pushing member 120, and the other end of the second metal wire penetrates through four holes of the second pushing member 120, then penetrates through three holes, and then penetrates through an outer wall of the second pushing member 120 to a hole of the second pushing member 120, and after being converged with one end of the second metal wire 220, the first metal wire is locked and fixed together by the first stud 300 and the fixing member 400 in the second pushing member 120. The threading mode can enable the upper side and the lower side of the wound to be stressed more uniformly, and is beneficial to wound contraction and wound repair.
