Description

Technical Field

[0001] The present application relates to the field of criminal investigation technology, and in particular to a suture needle. Background Art

[0002] At present, in the process of autopsy, suturing the anatomical incision is an inevitable step after the autopsy. The incision after the autopsy is usually sutured manually with a suture needle and sutures.

[0003] The suture needles used for corpses are different from the straight needles used for sewing clothes, and are also different from the curved needles used by clinical doctors during surgery. The suture needles used by forensic doctors are directly held in the hands when sewing, without the use of a needle holder. The suture thread used is also thicker than that used for sewing clothes, which results in greater resistance between the suture needle and soft tissue during the suturing process, resulting in low suturing efficiency. Utility Model Content

[0004] Based on this, it is necessary to provide a suture needle to solve the problem of low suturing efficiency of existing cadaver suture needles.

[0005] The suturing needle provided in the present application comprises a needle tip, a needle body and a needle tail connected in sequence; the end of the needle tip away from the needle body is at least partially arc-shaped, and the needle tip is sharpened on no less than three sides; the width of the needle tip first gradually increases and then gradually decreases in the direction away from the needle body; the width of the needle body and the width of the needle tail are both smaller than the maximum width of the needle tip; a wire retaining groove is provided on the needle tail, and the wire retaining groove is used to fix the suture thread.

[0006] The suture needle disclosed in the present application has a needle tip, a needle body and a needle tail connected in sequence, and the width of the needle tip gradually increases and then gradually decreases in the direction away from the needle body. The tip width of the needle tip is small and is easy to insert into the surface of the soft component. The needle tip is provided with blades on no less than three sides. After the needle tip is inserted into the soft component, the blades on the needle tip cut the soft tissue, and the width of the needle body and the width of the needle tail are both smaller than the maximum width of the needle tip, so that a larger cavity is formed in the soft tissue after the needle tip penetrates, and the needle body and the needle tail can easily pass through the soft tissue, reducing the resistance of the soft tissue to the needle tail. Even if the suture line is thicker in the suture of the corpse, it can easily penetrate the soft tissue with the suture needle, thereby reducing the difficulty of operation of the forensic doctor in suturing the corpse and improving work efficiency.

[0007] In one embodiment, the needle tip includes a first tip segment and a second tip segment, the first tip segment, the second tip segment and the needle body are connected in sequence, the first tip segment is arc-shaped, and the width of the first tip segment gradually decreases in the direction away from the second tip segment.

[0008] The suture needle in the above embodiment further defines that the needle tip is composed of a first tip segment and a second tip segment, the first tip segment is of arc-shaped design, and the second tip segment extends along the direction of the needle body and the needle tail. The first tip segment has a certain arc shape, which makes it easier for the forensic doctor to pierce the skin when dissecting and suturing the corpse.

[0009] In one embodiment, the cross section of the needle tip is triangular.

[0010] In one embodiment, a thumb grip surface and an index finger grip surface are formed on the needle body, and both the thumb grip surface and the index finger grip surface are in the shape of crow's feet.

[0011] The suture needle in the above embodiment is further defined as having a thumb grip surface and an index finger grip surface formed on the needle body for the convenience of the forensic doctor to hold the needle. The thumb grip surface and the index finger grip surface are both designed in a crow's foot shape, which not only increases the friction when the forensic doctor holds the needle, but also facilitates the forensic doctor to use the suture needle for puncture and thread pulling, reduces the possibility of needle dropping, and makes forensic work safer, but also does not increase the friction when the suture needle passes through the skin.

[0012] In one embodiment, the needle tail is in the shape of an elongated strip, and the cross section of the needle tail is in the shape of a rounded rectangle.

[0013] The suture needle in the above embodiment further defines that the needle tail is in the shape of a long strip, and the cross-section of the needle tail is in the shape of a rounded rectangle. Specifically, the top and bottom of the needle tail surface are both flat designs, and both sides of the needle tail surface are both arc-shaped designs. The traditional needle tail adopts a cylindrical design. The gloves of the forensic doctor after the autopsy are usually sticky with grease or water, making it difficult for the forensic doctor to hold the suture needle tightly, which is not conducive to piercing the skin. In addition, if the needle slips, it is easy to injure the forensic doctor himself, causing occupational exposure. Based on the above design, the friction between the forensic doctor's hand and the needle tail can be increased, and at the same time, it is not easy to damage the gloves worn by the forensic doctor.

[0014] In one of the embodiments, anti-slip grooves are arranged on the surface of the needle tail.

[0015] The suture needle in the above embodiment is further limited to having anti-slip grooves on the surface of the needle tail to increase the friction between the surface of the needle tail and the hand of the forensic doctor.

[0016] In one of the embodiments, a needle eye is formed on the surface of the needle tail, and the needle eye is communicated with the wire clamping groove.

[0017] The suture needle in the above embodiment is further defined as having a needle eye on the surface of the needle tail, which is connected to a thread retaining groove for fixing the suture thread. The suture thread can be assembled into the thread retaining groove along the needle eye on the surface of the needle tail, and there is no need to align the threading port for threading, thereby improving work efficiency.

[0018] In one embodiment, the needle eye is distributed on the left side wall of the needle tail or the right side wall of the needle tail.

[0019] The suture needle in the above embodiment further limits the needle eye to be distributed on the left wall or the right wall of the needle tail; specifically, the distribution of the needle eye on the needle tail can be adjusted according to the dominant hand of the forensic doctor, so as to avoid the needle eye contacting the forensic doctor's gloves and scratching the gloves.

[0020] In one embodiment, the width of the wire clamping groove gradually decreases in a direction away from the needle body.

[0021] The suture needle in the above embodiment further defines that the width of the wire clamping groove gradually decreases in the direction away from the needle body, so that as the suture needle moves, the suture thread moves from the side with the larger width of the wire clamping groove to the side with the smaller width of the wire clamping groove, thereby gradually clamping the suture thread and preventing the suture thread from falling off the suture needle easily.

[0022] In one of the embodiments, the opening of the needle eye is arranged obliquely, and the oblique direction is toward the side of the wire clamping slot with a smaller width.

[0023] The suture needle in the above embodiment is further defined such that the opening of the needle eye is inclined toward the side of the wire clamping slot with a smaller width, so that the suture thread can slide into the wire clamping slot along the inclined direction of the needle eye opening and be clamped with the wire clamping slot.

[0024] In one of the embodiments, a guide sliding surface is formed on the needle eye at an end close to the wire clamping slot with a smaller width, and the guide sliding surface faces an end of the wire clamping slot with a larger width.

[0025] The suture needle in the above embodiment further defines a guide surface formed at the end of the needle eye close to the smaller width of the wire retaining groove, and the guide surface is inclined with the inclination direction toward the end of the larger width of the wire retaining groove. When the needle eye penetrates the skin, the guide surface is pressed against the soft tissue to prevent the soft tissue from entering the needle eye and causing a jam in the penetration process.

[0026] In one embodiment, the wire clamping slot is divided into a first slot section, a second slot section and a third slot section which are connected in sequence, the third slot section is the shortest distance from the needle body, and the connection point between the wire clamping slot and the needle eye is distributed on the second slot section.

[0027] The suture needle in the above embodiment further defines that the connection between the wire holding groove and the needle eye is distributed on the second groove section. When the suture thread slides along the opening of the needle eye and falls into the wire holding groove, when the suture needle penetrates the soft tissue, the suture thread may move from the first groove section to the third groove section under the traction of the needle tail. Since the connection between the wire holding groove and the needle eye is distributed on the second groove section, the suture thread can stay in the third groove section and will not fall off directly from the second groove section through the needle eye, thereby ensuring the stability of the connection between the suture thread and the suture needle.

[0028] In one of the embodiments, a wire groove is provided on the front and back sides of the needle tail, the wire groove is distributed at the tail end of the needle tail, and the wire groove is connected to the wire clamping groove in an arc transition.

[0029] The suture needle in the above embodiment further defines that a wire groove connected to the wire clamping groove is provided at the tail end of the needle, and the suture thread is received in the wire groove during the process of the needle tail penetrating the soft tissue to reduce the friction between the suture thread and the soft tissue.

[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0039] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0040] like Figures 1 to 4As shown, this embodiment provides a suture needle, comprising a needle tip 1, a needle body 2 and a needle tail 3 connected in sequence, wherein the end of the needle tip 1 away from the needle body 2 is at least partially arc-shaped, and the needle tip 1 is sharpened on no less than three sides; the width of the needle tip 1 gradually increases and then gradually decreases in the direction away from the needle body 2; the width of the needle body 2 and the width of the needle tail 3 are both smaller than the maximum width of the needle tip 1; a wire retaining groove 310 is provided on the needle tail 3, and the wire retaining groove 310 is used to fix the suture thread.

[0041] Among them, the needle tip 1 of the suture needle can be used to pick and cut the skin during skin suturing, so that it is easier to penetrate the soft component; specifically, the tip width of the needle tip 1 is small, which is easy to insert into the surface of the soft component, and then the soft tissue is cut by the multi-sided blades on the needle tip 1, so that the needle tip 1 can smoothly penetrate the soft tissue.

[0042] Because the width of the needle tip 1 gradually increases and then gradually decreases in the direction away from the needle body 2, and the width of the needle body 2 and the width of the needle tail 3 are both smaller than the maximum width of the needle tip 1, the width of the cavity formed after the needle tip 1 passes through the soft tissue is larger than the widths of the needle body 2 and the needle tail 3, thereby allowing the needle body 2 and the needle tail 3 to easily pass through the soft tissue, reducing the resistance of the soft tissue to the needle tail 3.

[0043] The needle tip 1 can be made of high-hardness steel, such as stainless steel, high-carbon steel, etc., to increase the hardness of the needle tip 1 and prevent the needle tip 1 from becoming blunt and deforming.

[0044] The suture needle disclosed in the present application comprises a needle tip 1, a needle body 2 and a needle tail 3 which are connected in sequence, and the width of the needle tip 1 gradually increases and then decreases in the direction away from the needle body 2. The tip width of the needle tip 1 is relatively small, and it is easy to insert into the surface of a soft component. Blades are arranged on at least three sides of the needle tip 1. After the needle tip 1 is inserted into the soft component, the blades on the needle tip 1 cut the soft tissue, and the widths of the needle body 2 and the needle tail 3 are both smaller than the maximum width of the needle tip 1, so that a larger cavity is formed in the soft tissue after the needle tip 1 penetrates, and the needle body 2 and the needle tail 3 can easily pass through the soft tissue, thereby reducing the resistance of the soft tissue to the needle tail 3, and even if the suture thread is relatively thick during suturing of a corpse, it can easily penetrate the soft tissue along with the suture needle, thereby reducing the difficulty of operation of forensic doctors during autopsy and suturing of corpses, and improving work efficiency.

[0045] like Figures 1 to 3 As shown, in addition to the features of the above embodiments, this embodiment further defines: the needle tip 1 includes a first tip segment 11 and a second tip segment 12, the first tip segment 11, the second tip segment 12 and the needle body 2 are connected in sequence, the first tip segment 11 is arc-shaped, and the width of the first tip segment 11 gradually decreases in the direction away from the second tip segment 12.

[0046] The needle tip 1 is composed of a first tip section 11 and a second tip section 12. The first tip section 11 is designed to be arc-shaped, and the second tip section 12 extends along the direction of the needle body 2 and the needle tail 3. The first tip section 11 has a certain arc shape, which makes it easier for the forensic doctor to pierce the skin when dissecting and suturing the corpse.

[0047] like Figures 1 to 3 As shown, in addition to the features of the above embodiments, this embodiment is further defined as follows: the cross section of the needle tip 1 is in a triangular shape.

[0048] Among them, the cross-section of the needle tip 1 is triangular, that is, there are three sharp edges on the needle tip 1. For example, the top and left and right sides of the needle tip 1 are all sharpened. After the tip of the needle tip 1 punctures the skin surface, the inner soft component is cut by the edge on the needle tip 1, so that a larger cavity is formed in the soft component after the needle tip 1 penetrates, so that the needle body 2 and the needle tail 3 can easily penetrate.

[0049] like Figure 1 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that: a thumb grip surface 21 and an index finger grip surface 22 are formed on the needle body 2, and both the thumb grip surface 21 and the index finger grip surface 22 are in the shape of crow's feet.

[0050] The needle body 2 is provided with a thumb grip surface 21 and an index finger grip surface 22 for the forensic doctor to hold the needle. The thumb grip surface 21 and the index finger grip surface 22 are both designed in a fishtail pattern, which not only increases the friction when the forensic doctor holds the needle, but also facilitates the forensic doctor to use the suture needle for puncture and thread pulling, reduces the possibility of needle drop, and makes forensic work safer, but also does not increase the friction when the suture needle passes through the skin. It should be noted that the fishtail structure on the thumb grip surface 21 and the index finger grip surface 22 can be designed differently according to the different sizes of the thumb and index finger of the human body, such as the different sizes of the arc angles.

[0051] In addition, there are arc transitions between the thumb grip 21 and the needle tail 3 and between the index finger grip 22 and the needle tail 3, and the connection between the thumb grip 21 and the index finger grip 22 is an arc transition on the side close to the needle tail 3, so as to reduce the risk of cutting the operator by the edges formed by the thumb grip 21 and the index finger grip 22, and at the same time reduce the friction of the needle body 2 when penetrating the skin.

[0052] like Figure 1 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the needle tail 3 is in the shape of an elongated strip, and the cross section of the needle tail 3 is in the shape of a rounded rectangle.

[0053] Among them, the needle tail 3 is in the shape of a long strip, and the cross-section of the needle tail 3 is in the shape of a rounded rectangle. Specifically, the top and bottom of the surface of the needle tail 3 are both flat designs, and both sides of the surface of the needle tail 3 are both arc-shaped designs; the traditional needle tail 3 adopts a cylindrical design. The gloves of the forensic doctor after the autopsy are usually stained with grease or water, which makes it difficult for the forensic doctor to hold the suture needle tightly, resulting in inconvenience for piercing the skin. In addition, if the needle slips, it is easy to injure the forensic doctor himself, causing occupational exposure. Based on the above design, the friction between the forensic doctor's hand and the needle tail 3 can be increased, and at the same time, it is not easy to damage the gloves worn by the forensic doctor.

[0054] In addition to the features of the above embodiment, this embodiment further defines that: anti-slip grooves are provided on the surface of the needle tail 3 .

[0055] The surface of the needle tail 3 is provided with anti-skid patterns to increase the friction between the surface of the needle tail 3 and the hand of the forensic doctor. For example, the anti-skid patterns can be formed by herringbone anti-skid patterns, thereby achieving one-way anti-skid, facilitating the forensic doctor to perform puncture and thread pulling with a suture needle, reducing the possibility of needle dropping, and making forensic work safer.

[0056] like Figures 1 to 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: a needle eye 301 is opened on the surface of the needle tail 3, and the needle eye 301 is connected to the wire clamping groove 310.

[0057] Among them, the surface of the needle tail 3 is provided with a needle eye 301, which is connected to the thread clamping groove 310 for fixing the suture thread. The suture thread can be assembled into the thread clamping groove 310 along the needle eye 301 on the surface of the needle tail 3, and it is no longer necessary to align the threading port for threading, thereby improving work efficiency. Specifically, since the needle eye 301 is distributed on the surface of the needle tail 3, the forensic doctor only needs to place the suture thread against the surface of the needle tail 3 and move the suture thread to the needle eye 301, and the suture thread slides through the needle eye 301 into the thread clamping groove 310 to complete the assembly.

[0058] like Figures 1 to 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the needle eye 301 is distributed on the left wall of the needle tail 3 or the right wall of the needle tail 3.

[0059] Among them, the needle eye 301 is distributed on the left side wall or the right side wall of the needle tail 3; specifically, the distribution of the needle eye 301 on the needle tail 3 can be adjusted according to the dominant hand of the forensic doctor. For example, when the dominant hand of the forensic doctor is the right hand, the needle eye 301 is distributed on the left side wall of the needle tail 3. Since the thumb and index finger of the forensic doctor's right hand hold the needle body 2, the palm part of the right hand is located above the needle tail 3. Based on the opening direction of the needle eye 301 obliquely toward the side with the smaller width of the wire clamping slot 310, the needle eye 301 can be prevented from contacting the forensic doctor's gloves and scratching the gloves; if the dominant hand of the forensic doctor is the left hand, the needle eye 301 is distributed on the right side wall of the needle tail 3.

[0060] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the width of the wire clamping groove 310 gradually decreases in the direction away from the needle body 2.

[0061] Among them, the width of the wire clamping groove 310 gradually decreases in the direction away from the needle body 2, so that the suture thread moves from the side with the larger width of the wire clamping groove 310 to the side with the smaller width of the wire clamping groove 310 as the suture needle moves, thereby gradually clamping the suture thread and preventing the suture thread from falling off the suture needle easily.

[0062] As shown Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the opening of the needle eye 301 is inclined, and the oblique cutting direction is toward the side of the wire clamping slot 310 with a smaller width.

[0063] The opening of the needle eye 301 is inclined toward the side of the wire clamping slot 310 with a smaller width, so that the suture thread can slide into the wire clamping slot 310 along the inclined direction of the opening of the needle eye 301 and be clamped with the wire clamping slot 310 .

[0064] like Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the needle eye 3 is formed with a guide sliding surface 314 at the end close to the wire clamping groove 310 with a smaller width, and the guide sliding surface 314 faces the end of the wire clamping groove 310 with a larger width.

[0065] Among them, a guide surface 314 is formed at the end of the needle eye 301 with a smaller width close to the wire clamping groove 310, and the guide surface 314 is designed to be inclined, with the inclination direction toward the end of the wire clamping groove 310 with a larger width. When the needle eye 301 penetrates the skin, the guide surface 314 presses against the soft tissue to prevent the soft tissue from entering the needle eye 301 and causing a jam in the penetration process.

[0066] like Figure 3 and Figure 4 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines that: the wire clamping slot 310 is divided into a first slot section 311, a second slot section 312 and a third slot section 313 which are connected in sequence, the third slot section 313 is at the shortest distance from the needle body 2, and the connection between the wire clamping slot 310 and the needle eye 301 is distributed on the second slot section 312.

[0067] Among them, the connection point between the wire holding slot 310 and the needle eye 301 is distributed on the second slot section 312. When the suture thread slides along the opening of the needle eye 301 and falls into the wire holding slot 310, when the suture needle penetrates the soft tissue, the suture thread may move from the first slot section 311 to the third slot section 313 under the traction of the needle tail 3. Since the connection point between the wire holding slot 310 and the needle eye 301 is distributed on the second slot section 312, the suture thread can stay in the third slot section 313 and will not fall off directly from the second slot section 312 through the needle eye 301, thereby ensuring the stability of the connection between the suture thread and the suture needle.

[0068] like Figure 1 , 3 As shown in FIG. 4 , a wire groove 320 is provided on the front and back sides of the needle tail 3 . The wire groove 320 is distributed at the tail end of the needle tail 3 . The wire groove 320 is connected to the wire clamping groove 310 by an arc transition.

[0069] The tail end of the needle tail 3 is provided with a guide wire groove 320 connected to the guide wire groove 310. When the needle tail 3 penetrates the soft tissue, the suture is received in the guide wire groove 320 to reduce friction between the suture and the soft tissue.

[0070] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present utility model patent shall be subject to the attached claims.
