Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to a hernia needle for children's inguinal hernia. Background Art

[0002] Inguinal hernia in children refers to a disease in which the abdominal organs (usually the intestines) protrude into the groin area due to weak areas of abdominal wall muscles or tissues during infancy or childhood. This disease is relatively common in infants and young children, usually due to incomplete development or weakness of the abdominal wall muscles, which makes it easy for internal organs to protrude.

[0003] In the related art, in order to repair inguinal or abdominal wall hernias, a minimally invasive treatment method of hernia needle surgery is often used. It does not require a large incision or mesh implantation. In this operation, the doctor inserts a thin needle through the hernia defect and uses a special thread on the puncture needle to fix the abdominal viscera to repair the hernia. In order to prevent the puncture needle from puncturing the peritoneum, it is necessary to inject normal saline at the same time during the insertion of the inner needle. However, for the existing hernia needle, it is found in actual application that the injection of normal saline does not cooperate well with the insertion of the inner needle. At the same time, the hernia needle is used to hook out the lead wire for the ligation process. Due to the large diameter, the sharp and thick needle tip, it is easy to puncture blood vessels and peritoneum, and it is not easy to sneak outside the peritoneum. The hook at one end of the lead wire can easily pull the peritoneum and some tissues, causing tissue damage, etc., that is, there are problems of inconvenience in use and poor work efficiency. Utility Model Content

[0004] The utility model aims to solve the problems in the prior art that a hernia needle is not easy to sneak outside the peritoneum and the injection of physiological saline does not achieve better results. Therefore, a hernia needle for pediatric inguinal hernia is proposed.

[0005] In order to achieve the above-mentioned object, the embodiment of the present invention provides a hernia needle for pediatric inguinal hernia, comprising:

[0006] a second handle, wherein the second handle has a limiting hole formed along the thickness direction;

[0007] An outer sleeve, one end of which is fixedly connected to the end surface of the second handle and is coaxially arranged with the limiting hole, and a through hole is formed on the side surface of the outer sleeve;

[0008] a sleeve, coaxially fixedly connected to an end of the outer sleeve away from the second handle;

[0009] A transmission rod is partially inserted into the sleeve through the limiting hole;

[0010] An inner needle assembly is disposed in the outer sleeve and fixedly connected to one end of the transmission rod;

[0011] A liquid injection assembly is arranged at the through hole and selectively communicated with the inner cavity of the outer sleeve.

[0012] In some possible embodiments, the inner needle assembly includes:

[0013] a protrusion, the protrusion being fixedly connected to the end surface of the second handle;

[0014] A pressing block, the pressing block is fixedly connected to one end of the transmission rod;

[0015] A rotating base, one end of which contacts the pressing block;

[0016] A fixed ring is arranged in the outer sleeve, and an elastic member is provided in the cavity between the fixed ring and the rotating base.

[0017] In some possible embodiments, a tooth groove and an inclined surface are provided at the bottom end of the protrusion, and a rotating block with an inclined surface is provided at the top end of the rotating base, and the rotating block can selectively slide into or out of the tooth groove.

[0018] In some possible embodiments, when the rotating block slides into or out of the tooth groove, the rotating base has different heights in the vertical direction.

[0019] In some possible embodiments, the inner needle assembly further comprises an inner needle fixedly connected to the bottom end surface of the rotating base, and a groove is provided at one end of the inner needle away from the rotating base.

[0020] In some possible embodiments, both ends of the elastic member are fixedly connected to the rotating base and the fixing ring respectively, and the rotating base is slidably connected to the outer sleeve.

[0021] In some possible embodiments, when the rotating base slides downward, the elastic member is in a compressed state.

[0022] In some possible embodiments, the injection assembly includes:

[0023] A first sleeve, fixed and penetrating the side wall of the outer sleeve;

[0024] a third sleeve, coaxially disposed in the first sleeve;

[0025] The second sleeve is coaxial with the third sleeve and is slidably connected thereto.

[0026] In some possible embodiments, one end of the second sleeve is sealed with a supporting plate, and the supporting plate can selectively abut against an end surface of the first sleeve close to the inner side of the outer sleeve.

[0027] In some possible embodiments, the second sleeve is provided with an injection port on a side end surface close to the abutment plate.

[0028] Compared with the prior art, the technical solution provided by the embodiment of the present invention includes at least the following beneficial effects or advantages:

[0029] 1) Through the setting of the outer sleeve and the cannula, the hernia needle can be sneaked outside the peritoneum to protect the blood vessels and peritoneum. Through the setting of the inner needle assembly, the thumb presses the first handle, the transmission rod slides downward, and the pressing block is driven by the force of the transmission rod to carry the sliding block, and the sliding block moves downward along the track groove set by the protrusion. When the pressing block contacts the rotating block, the rotating base slides downward, and the rotating block rotates on the rotating base. The rotating force generated by the contact between the inclined surface of the rotating block and the inclined surface of the protrusion makes the tooth groove of the protrusion fit with the top inclined surface of the rotating block. The spring under the rotating base is compressed and deformed, so that the inner needle extends from the cannula. The inner needle is protected by the cannula and is not easily deformed. On the contrary, when the medical staff When the first handle is pressed for the first time, the pressing block contacts the rotating block, the rotating base slides downward, the rotating block rotates, and the inclined surface of the rotating block contacts and slides with the bottom tooth groove of the protrusion, the inclined surface of the rotating block returns to the sliding groove of the protrusion, and the spring under the rotating base is compressed and rebounds, and the inner needle is retracted into the sleeve. The inner needle assembly reduces the problem of the medical staff's thumb pressing the first handle for a long time. The medical staff can operate by clamping the second handle with their fingers, which improves the comfort of the medical staff. When in use, the medical staff can place the lead in the groove and send the lead into the patient's body. When the lead needs to be hooked out, the lead can be hooked through the groove, which is convenient for both feeding and hooking the lead.

[0030] 2) When the inner needle is pushed into the patient's abdominal cavity or when cleaning is required, the hose is inserted through the first sleeve. When one end of the hose contacts the second sleeve, the ring is pushed, the spring between the second sleeve and the third sleeve is stressed, the second sleeve slides forward, and normal saline is injected through the second sleeve. The normal saline flows downward through the injection port, the fixed ring does not fit the inner needle, and the normal saline is injected into the patient's body through the sleeve. The injection of normal saline cooperates well with the pushing of the inner needle, which reduces the operation of medical staff, avoids the patient being inserted by the hook needle for the second time, and improves the work efficiency of medical staff.

[0031] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0052] See also Figures 1 to 6 The present embodiment provides a hernia needle for pediatric inguinal hernia, comprising: a transmission rod 2, a first handle 1 being provided at one end of the transmission rod 2, the shape of the first handle 1 being able to be set to be elliptical, circular or rectangular, etc., and being selected according to actual needs, a second handle 5, the second handle 5 being provided with a limiting hole along the thickness direction, an outer sleeve 6, one end of the outer sleeve 6 being fixedly connected to the end face of the second handle 5, and being coaxially arranged with the limiting hole, a through hole being provided on the side surface of the outer sleeve 6; a sleeve 7 being coaxially fixedly connected to the end of the outer sleeve 6 away from the second handle 5, and through the arrangement of the outer sleeve 6 and the sleeve 7, the hernia needle can be sneaked outside the peritoneum to protect the blood vessels and peritoneum.

[0053] like Figure 1 and Figure 2 As shown, the transmission rod 2 is partially inserted into the sleeve 6 through the limiting hole, and the transmission rod 2 and the sleeve 6 are coaxially arranged, the inner needle assembly 3 is arranged in the outer sleeve 6 and fixedly connected to one end of the transmission rod 2. It can be understood that the transmission rod 2 can drive the inner needle assembly 3 to slide along the inner cavity of the outer sleeve 6, and the injection assembly 4 is arranged at the through hole and selectively connected to the inner cavity of the outer sleeve 6. It should be noted that the injection assembly 4 can selectively connect with the external infusion tube.

[0054] In some embodiments, as Figures 3 and 4 The inner needle assembly 3 includes a protrusion 301, a pressing block 302, a rotating base 304 and a fixing ring 305. The protrusion 301 is fixedly connected to the end face of the second handle 5, the pressing block 302 is fixedly connected to one end of the transmission rod 2, one end of the rotating base 304 is in contact with the pressing block 302, the fixing ring 305 is arranged in the outer sleeve 6, and an elastic member is provided in the gap between the fixing ring 305 and the rotating base 304.

[0055] It should be noted that the two ends of the elastic member are fixedly connected to the rotating base 304 and the fixed ring 305 respectively, and the rotating base 304 is slidably connected to the outer sleeve 6. The elastic member can be a spring or an elastic sheet, and the specific selection can be made according to actual needs. During the downward sliding of the rotating base 304, the elastic member is in a compressed state. Specifically, the state of the elastic member can be in the original state or the compressed state.

[0056] Optionally, a tooth groove and an inclined surface are provided at the bottom end of the protrusion 301, and a rotating block 303 with an inclined surface is provided at the top of the rotating base 304. The rotating block 303 can selectively slide in or out of the tooth groove. When the rotating block 303 slides in or out of the tooth groove, the rotating base 304 has different heights in the vertical direction. The inner needle assembly 3 also includes an inner needle 306 fixedly connected to the bottom end surface of the rotating base 304, and a groove 307 is provided at the end of the inner needle 306 away from the rotating base 304.

[0057] Specifically, the pressing block 302 is coaxially slidably arranged within the central axis of the rotating block 303. The shape of the pressing block 302 can be cylindrical. A plurality of sliding blocks 308 are arranged at intervals on the surface of the pressing block 302, and a plurality of vertical guide grooves are arranged at annular intervals on the rotating block 303. The sliding block 308 extends into the guide groove and can slide in the vertical direction along the guide groove, thereby playing a certain limiting role in the sliding of the pressing block 302.

[0058] In addition, the bottom end of the protrusion 301 is provided with a tooth groove shape which can be the same as the shape of the rotating block 303. When the pressing block 302 is pressed downward by an external force, the inclined surface of the rotating block 303 cooperates with the inclined surface of the pressing block 302, so that the rotating block 303 rotates and moves downward. When the pressing block 302 rotates to the tooth groove position of the protrusion 301, the pressing block 302 can rebound into the tooth groove, thereby fixing the rotating base 304 after moving downward. At this time, the inner needle 306 extends from one end of the sleeve 7 away from the groove 307 set at one end of the rotating base 304.

[0059] When the push button 302 is in contact with the rotating block 303, the rotating base 304 slides downward, and the rotating block 303 rotates on the rotating base 304. The rotating force generated by the contact between the inclined surface of the rotating block 303 and the inclined surface of the protrusion 301 makes the tooth groove of the protrusion 301 fit with the top inclined surface of the rotating block 303. The spring under the rotating base 304 is compressed and deformed, causing the inner needle 306 to extend from the cannula 7. The inner needle 306 is protected by the cannula 7 and is not easily deformed. On the contrary, when the medical staff When the first handle 1 is pressed for the first time, the pressing block 302 contacts the rotating block 303, the rotating base 304 slides downward, the rotating block 303 rotates, and the inclined surface of the rotating block 303 contacts and slides with the bottom tooth groove of the protrusion 301, the inclined surface of the rotating block 303 returns to the sliding groove of the protrusion 301, and the spring under the rotating base 304 is compressed and rebounds, and the inner needle 306 is retracted into the sleeve 7. The inner needle assembly 3 reduces the problem of the medical staff's thumb pressing the first handle for a long time. The medical staff can operate by clamping the second handle 5 with their fingers, which improves the comfort of the medical staff. When in use, the medical staff can place the lead wire in the groove 307 and send the lead wire into the patient's body. When the lead wire needs to be hooked out, it can be hooked through the groove 307, which is convenient for both feeding and hooking the wire.

[0060] Optional, such as Figure 5 and Figure 6 As shown, the liquid injection assembly 4 includes a first sleeve 401, a second sleeve 402 and a third sleeve 403; the first sleeve 401 is fixed and penetrates the side wall of the outer sleeve 6, the third sleeve 403 is coaxially arranged in the first sleeve 401, and the second sleeve 402 and the third sleeve 403 are coaxial and slidably connected.

[0061] Specifically, one end of the second sleeve 402 is sealed with a support plate 406, the shape of the support plate 406 is circular, and the diameter of the support plate 406 is larger than the diameter of the first sleeve 401. The third sleeve 403 is coaxially arranged in the first sleeve 401 and fixedly connected to the first sleeve 401. One end of the third sleeve 403 is connected to the support plate 406 through a spring.

[0062] It can be understood that the diameter of the second sleeve 402 is smaller than that of the third sleeve 403, the spring is sleeved on the surface of the second sleeve 402, a ring 404 is fixedly provided at one end of the side surface of the second sleeve 402, the ring 404 is slidably connected to the inner wall of the right end of the third sleeve 403, and an injection port 405 is opened on the side end surface of the second sleeve 402 near the abutment plate 406.

[0063] When the inner needle is pushed into the patient's abdominal cavity or when cleaning is required, the hose is inserted through the first sleeve 401. When one end of the hose contacts the second sleeve 402, the ring 404 is pushed, and the spring between the second sleeve 402 and the third sleeve 403 is stressed. The second sleeve 402 slides forward, and normal saline is injected through the second sleeve 402. The normal saline flows downward through the injection port 405. The fixing ring 305 does not fit the inner needle 306, and the normal saline is injected into the patient's body through the sleeve 7. This reduces the operation of medical staff, avoids the patient being inserted by the hook needle for the second time, and improves the work efficiency of medical staff.
