Description

Technical Field

[0001] The utility model relates to the technical field of orthopedic medical devices, and particularly relates to a minimally invasive surgical tool set for pelvic metastatic cancer. Background Art

[0002] Both the pelvis and the surrounding acetabulum are important cross-linked parts of the human locomotor system and are also the predilection sites of bone metastatic cancer. The pelvis is a common site of tumor bone metastasis. Once the tumor metastasizes to the surrounding acetabulum, pelvic metastatic cancer often causes significant pain and limited mobility. In mild cases, it is manifested as severe pain, limited movement, inability to walk, and decreased quality of life, etc. In severe cases, it is manifested as pathological fracture and loss of motor ability, seriously affecting the patient's quality of life and even accelerating death.

[0003] Currently, there is a lack of effective methods for the treatment of pelvic bone metastatic cancer, and the choices are very limited, including surgical treatment. Existing surgical treatment methods include tumor resection, fixation of pathological fractures, reconstruction of hip joint prosthesis, and even amputation. The existing surgical treatment methods have large trauma, much bleeding, high complication incidence and perioperative mortality, and high medical expenses. The former has a long postoperative rehabilitation process, insignificant symptom relief, and loss of independent living ability. More importantly, the interruption of systemic treatment leads to uncontrolled progression of the tumor, directly threatening the effective survival time of the patient. Therefore, the clinical dilemma is very significant. The external guiding frame of the intramedullary nail with percutaneous internal fixation and reinforcement around the acetabulum disclosed in the invention application with the application number 202311786273.9, as a new surgical technique and internal fixation material, has the characteristics of small trauma, few complications and low cost, and can quickly and effectively relieve the symptoms of patients with pelvic metastatic cancer, enabling them to resume daily life as soon as possible, so as to continue to connect with systemic treatment.

[0004] In the development and application of clinical surgical operations, there are many difficulties involved in percutaneous puncture, aiming, positioning, fixation, etc., resulting in the need for many surgical tools in the surgical treatment of pelvic bone metastatic cancer, including guide needles, aiming devices, head probes, etc. There are many and miscellaneous surgical tools on the market. Although some surgical tools such as guide needles, aiming devices, head probes, etc. can be used in the surgical treatment of pelvic bone metastatic cancer and can almost meet the basic requirements such as aiming, positioning, and fixation, due to the particularity of the surgical treatment of pelvic bone metastatic cancer, there are special requirements for surgical tools. For example, during the surgical process, due to body position, tissue obstruction, and difficult fluoroscopy, it is often impossible to correctly judge the position of the guide needle. Sometimes doctors have to rely on manual feeling to judge the depth and position of the guide needle. In this case, it would be great if the depth and position of the guide needle could be indirectly displayed. In addition, the surgical treatment of pelvic bone metastatic cancer also puts forward higher requirements for minimizing the minimally invasive of the aiming device and the need for the head probe to detect the nail track condition of the intramedullary nail, etc.

[0005] Since minimally invasive surgery for pelvic bone metastasis requires many and diverse surgical tools, the surgical tools specifically used for minimally invasive surgery for pelvic bone metastasis are not centralized, resulting in doctors having to purchase them separately, and the purchased multiple surgical tools are then scattered everywhere. Not only are the purchased surgical tools not compatible with minimally invasive surgery for pelvic bone metastasis, but they are also unsatisfactory for doctors to use, and it is not conducive to the management of surgical tools, thereby reducing the efficiency of the operation.

[0006] Ultimately, it is because there is a lack of surgical tool sets on the market that are suitable for minimally invasive surgery for pelvic bone metastasis. Utility Model Content

[0053] Embodiment 2 of the present utility model provides a method for using a minimally invasive surgical tool set for pelvic metastatic cancer, which adopts the minimally invasive surgical tool set of Embodiment 1.

[0054] An external guiding frame for a percutaneous internal fixation and strengthened intramedullary nail around the acetabulum, disclosed in the invention application with the application number 202311786273.9, includes a general guiding frame. The general guiding frame includes an arc-shaped assembly. The arc-shaped assembly includes a left arc-shaped guide plate, a middle guide plate, and a right arc-shaped guide plate. The two ends of the middle plate are detachably connected to the left arc-shaped guide plate and the right arc-shaped guide plate respectively to form an arc-shaped assembly by splicing; a cross-column nail catheter and an anterior column nail catheter are arranged on the left arc-shaped guide plate or the right arc-shaped guide plate, and at least one arc-shaped rod is connected to the middle plate. A posterior column nail catheter is fixed at the end of the arc-shaped rod; three internally fixed and strengthened intramedullary nails that are spatially staggered and arranged in a tripod-like pattern are implanted into the pelvic bone around the diseased acetabulum through the cross-column nail catheter, the anterior column nail catheter, and the posterior column nail catheter respectively, which can immediately and significantly relieve the pain symptoms of the patient and restore the motor function. These three internally fixed and strengthened intramedullary nails are respectively: the cross-column nail, the posterior column nail, and the anterior column nail. Among them, the cross-column nail refers to: passing through one of the areas between the anterior superior iliac spine and the anterior inferior iliac spine of the affected ilium, and starting from this point, passing through the top of the acetabulum, and reaching the sacroiliac joint along the cancellous bone in the greater sciatic notch but not passing through the joint surface. The posterior column nail refers to: passing through the ischial tuberosity of the buttock, and starting from the ischial tuberosity of the ischial tuberosity, along the inside of the ischial ramus bone, passing through the posterior wall of the acetabulum, and reaching the proximal end of the greater sciatic notch but not piercing the cortical bone. The anterior column nail refers to: passing through the iliac part of the acetabular apex, and starting from this point, passing through the acetabular roof and the anterior wall of the acetabulum, to the superior pubic ramus of the acetabular apex, and ending at the affected pubic symphysis but not piercing the cortical bone. The invention application with the application number 202311786273.9, "An external guiding frame for a percutaneous internal fixation and strengthened intramedullary nail around the acetabulum", solves the problems existing in the existing treatment methods for metastatic cancer around the acetabulum, such as long operation time, high incidence of surgical complications and wound complications, slow patient recovery, etc. due to open surgery, as well as the problems of high technical difficulty, long learning curve, and low complication tolerance rate during the operation of the tripod-like internally fixed and strengthened intramedullary nail by hand, significantly improving the surgical accuracy, reducing the surgical technical difficulty, and shortening the operation time, thus benefiting the patients. Using general intramedullary nails as the cross-column nail and the posterior column nail respectively, the usage method of this minimally invasive surgical tool set for pelvic metastatic cancer includes the general intramedullary nail implantation method for the pelvis and the anterior column intramedullary nail implantation method for the pelvis.

[0055] Among them, the general intramedullary nail implantation method for the pelvis includes the following steps:

[0056] Step A1: The patient lies supine on the fluoroscopy operating table. After successful anesthesia and disinfection, the affected hip and knee are flexed to expose the ischial tuberosity:

[0057] Step A2: At the expected position near the nail (such as the ischial tuberosity), use a scalpel to cut the skin and bluntly separate the muscle tissue to the bone surface;

[0058] Step A3: Insert the incision with the honeycomb eccentric aiming device 4 combined with the skin protection sleeve 6, and press against the cortical bone;

[0059] Step A4: Insert the guide pin 1 through the central hole of the honeycomb eccentric aiming device 4. Gradually observe the position and penetration depth of the guide pin 1 under fluoroscopy.

[0060] Step A5: Combine the intraoperative fluoroscopy position to comprehensively judge the position of the guide pin 1. If it is not ideal, the honeycomb eccentric aiming device 4 or the horizontal eccentric aiming device 5 can be used respectively to insert a new guide pin 1, so as to adjust the position of the original guide pin 1;

[0061] Step A6: After determining that the position of the guide pin 1 is good, use the soft ball-tipped probe 2 or the hard ball-tipped probe 3 to explore the guide pin channel to ensure that the channel is a bony channel;

[0062] Step A7: Under the protection of the skin protection sleeve 6, use a hollow drill bit to expand the nail track of the guide pin 1 on the cortical bone;

[0063] Step A8: According to the length indicated by the guide pin 1, select a universal intramedullary nail of appropriate length, and gradually screw it in through a hollow hexagon screwdriver. Observe the nail insertion position under fluoroscopy to ensure that the enlarged part at the nail tail is tightly connected to the cortical bone, and then withdraw the guide pin 1;

[0064] Step A9: According to the clinical situation, connect a bone cement pressurized injection device to the nail tail. Under fluoroscopy, inject bone cement through the hollow channel inside the intramedullary nail, and let it flow out from the opening at the nail head to fill the gap between the intramedullary nail and the cortical bone. Dynamically observe the bone cement leakage situation under fluoroscopy.

[0065] Step A10: Irrigate the incision, suture the skin, and the operation is completed.

[0066] The method for implanting the anterior column intramedullary nail into the pelvis includes the following steps:

[0067] Step B1: The patient lies supine on the fluoroscopy operating table. After successful anesthesia and disinfection:

[0068] Step B2: At the intersection of the extension line of the trunk from the predicted near-nail position, such as the level of the greater trochanter of the femur, and the anterior superior iliac spine, use a scalpel to incise the skin and bluntly separate the muscle tissue to the bone surface;

[0069] Step B3: Apply the honeycomb eccentric aiming device 4, combined with the skin protection sleeve 6, to insert into the incision and press against the cortical bone;

[0070] Step B4: Insert the guide pin 1 through the central hole of the honeycomb eccentric aiming device 4. Gradually observe the position and penetration depth of the guide pin 1 under fluoroscopy.

[0071] Step B5: Combine with the intraoperative fluoroscopy position to comprehensively judge the position of the guide pin 1. If it is not ideal, the honeycomb eccentric aiming device 4 or the horizontal eccentric aiming device 5 can be used respectively to insert a new guide pin 1, so as to adjust the position of the guide pin 1;

[0072] Step B6: After determining that the position of the guide pin 1 is good, use the soft ball-tip probe 2 or the hard ball-tip probe 3 to explore the guide pin channel to ensure that the channel is a bony channel;

[0073] Step B7: Apply a hollow drill bit and expand the nail track of the guide pin 1 on the cortical bone under the protection of the skin protection sleeve 6;

[0074] Step B8: According to the length shown by the guide pin 1, select a front-column intramedullary nail of appropriate length, connect the intramedullary nail insertion tool, and gradually tap it in. Dynamically observe the position of the proximal nail under fluoroscopy, and hold the handle of the intramedullary nail insertion tool to adjust the insertion angle of the intramedullary nail to ensure that the enlarged part at the end of the nail is immersed in the cortical bone, withdraw the guide pin, and remove the insertion tool;

[0075] Step B9: Select a suitable end cap and screw it into the end of the front-column intramedullary nail to ensure that the end cap is locked with the front-column intramedullary nail through the thread, and its external thread is tightly connected to the cortical bone.

[0076] Step B10: Irrigate the incision, suture the skin, and the operation is completed.
